15:44:40 UTC - 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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=1
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68254 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x9891d90
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...

Hi, Can you repeat this output (and crash) on some other operating system. It would do if you can repeat it on a completely different Linux distribution. Thanks in advance.

Sinisa - Before I spend time on my part to set up required VMs, clone, build, etc., it would be really helpful if you told me the list of acceptable Linux distros, packaging an acceptable ubsan version. So that I don't waste my time in testing the wrong distros (such as Ubuntu 15.10 apparently :)
