LP:693387 - Signal 6 on shutdown on FreeBSD

I had installed 5.2.4 on FreeBSD 8.1-zfs, gcc 4.5.2

There is no problem with MySQL 5.1.54, but with MariaDB, I always got this when stopping mysqld.

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.

key_buffer_size=0
read_buffer_size=134217728
max_used_connections=3
max_threads=502
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 131602382 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
