Description
mysqld segfaults on startup.
Stack trace below.
It then restarts through mysqld_safe, and after that appears to be ok-ish with clients able to connect. But it's not in good shape. There may be InnoDB tables with corruption in this installation, which could be a possible trigger for the crash - however, a segfault is always a bug. An specific assert from InnoDB would be (although still annoying) more useful as then more context is shown.

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.

|
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: 5.5.43-MariaDB-1~trusty

key_buffer_size=16777216
|
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 = 352025 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went

terribly wrong...
