Debian Stretch, Mariadb 10.3.16, Mariadb ODBC Driver 3.1.1-ga
Description
The attached test-case for mariadb odbc driver 3.1.1 causes mariadb 10.3.16 server to crash with different stack-traces, this is indeed a problem of the odbc driver however the server shouldn't crash. I consider this bug critical because it is too easy to bring the server down and mdb 10.3 is about to become the new stable version of debian.
Edit: I have attached a better test segv_mdb_10_3_16_rel.test.patch, the first one didn't crash the release build of mdb server.
Stack-Trace One:
190623 13:03:51 [ERROR] mysqld got signal 11 ;
|
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.

read_buffer_size=131072
|
max_used_connections=2

max_threads=2050

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4639127 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
