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=16777216
read_buffer_size=3145728
max_used_connections=523
max_threads=800
thread_count=522
connection_count=522
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)max_threads = 9037821 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0
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...
stack_bottom = 0 thread_stack 0x40000
The manual page at http://dev.mysql./doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
