This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.2.38-MariaDB-debug-log
key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=153
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63104 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x62a000060270
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 10.2.38-MariaDB-debug-log key_buffer_size=1048576 read_buffer_size=131072 max_used_connections=1 max_threads=153 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)max_threads = 63104 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x62a000060270 Attempting backtrace. You can use the following information to find out where mysqld died.

because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 10.2.38-MariaDB-debug-log key_buffer_size=1048576 read_buffer_size=131072 max_used_connections=1 max_threads=153 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)max_threads = 63104 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x62a000060270 Attempting backtrace. You can use the following information to find out where mysqld died.

because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 10.2.38-MariaDB-debug-log key_buffer_size=1048576 read_buffer_size=131072 max_used_connections=1 max_threads=153 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)max_threads = 63104 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x62a000060270 Attempting backtrace. You can use the following information to find out where mysqld died.

because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 10.2.38-MariaDB-debug-log key_buffer_size=1048576 read_buffer_size=131072 max_used_connections=1 max_threads=153 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)max_threads = 63104 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x62a000060270 Attempting backtrace. You can use the following information to find out where mysqld died.

Reproducible on all kinds of builds as described above, on 10.2-10.6 with slight variations in the stack traces. Sometimes it also hangs.

Raising the priority in hope to get it fixed.
It's a nasty issue which affects release builds. The usual argument that real users don't encounter it, or they would have complained, doesn't apply here, as it isn't recognizable on non-ASAN builds. If it ends with a crash, MariaDB crash reporting doesn't handle well such errors, so there will be no stack trace or crashing query in the error log; and in addition to crashes, it can also lead to all kinds of confusing functional problems which are impossible to connect to this issue. For example, the last one I spent quite some time on was this:

10.5
MariaDB [(none)]> SELECT c.TABLE_SCHEMA, c.TABLE_NAME, c.COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS c WHERE c.TABLE_NAME = 't8_Aria' AND c.TABLE_SCHEMA IN ('advanced_db') ;
+--------------+------------+----------------+
\| TABLE_SCHEMA \| TABLE_NAME \| COLUMN_NAME \|

\| advanced_db \| t8_Aria \| col_year \|
+--------------+------------+----------------+
12 rows in set (0.001 sec)

Note the empty column name in I_S output. It is an unrelated table, not even a MyISAM table, but this would start happening after CHECK or OPTIMIZE on an unfortunate MyISAM table similar to one in the description. I've seen many other weird effects.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.2.38-MariaDB-debug-log
key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=153
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63104 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x62a000060270
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

210305 0:05:16 [ERROR] mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.2.38-MariaDB-debug-log
key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=153
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63104 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x62a000060270
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Same testcase on 11.5, CLI:

11.5.0 e4afa610539ae01164485554e2de839bea9de816 (Debug)
SIGSEGV\|my_hash_iterate\|safe_mutex_free_deadlock_data\|safe_mutex_destroy\|inline_mysql_mutex_destroy

11.5.0 e4afa610539ae01164485554e2de839bea9de816 (Optimized)
SIGSEGV\|l_find\|l_search\|lf_hash_search_using_hash_value\|MDL_map::find_or_insert

Agreed this is a high prio bug.

One small note that it might make sense to initialize only a newly added part of the realloc'ed buffer. Otherwise it's ok to push.

nikitamalyavin The buffer may be realloced at different location. Impairing code readability without any win (this is initialization stage, non-critical performance area) makes no sense to me.
