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=2097152
read_buffer_size=131072
max_used_connections=6
max_threads=151
thread_count=4
connection_count=4
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 
332346 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

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...
