Description
Hello and thank you for mariadb-5.3.12-Linux-x86_64.tar.gz
I added a comment in https://mariadb.atlassian.net/browse/MDEV-4409 mentioning two crashes I had today while running "SET GLOBAL key_cache_segments = 64;" on mariadb-5.3.12-Linux-x86_64.tar.gz on RHEL5. Vladislav Vaintroub pointed me at https://bugs.launchpad.net/maria/+bug/1008293 and I found the following changes

I have a RQG reproducer
# cat 3.yy

query_init:
|
SET GLOBAL key_buffer_size = 1024*1024;
|
thread1:
|
SET GLOBAL key_cache_segments = _digit;
|
|
|
query:
|
REPLACE INTO E(col_int_key, col_datetime_key) VALUES(1, NOW());
|
|
|
# End of RQG grammar

|
|
# Run as

|
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 http://kb.askmonty.org/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: 5.3.12-MariaDB-log
|
key_buffer_size=1048575
|
read_buffer_size=131072
|
max_used_connections=3
|
max_threads=152
|
thread_count=3
|
connection_count=3
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61369 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

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...
