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=536870912
read_buffer_size=131072
max_used_connections=1
max_connections=400
threads_connected=1
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 139468
4 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...
Cannot determine thread, fp=0xb, backtrace may not be correct.
Bogus stack limit or frame pointer, fp=0xb, stack_bottom=0xb30a0000, thread_stac
k=131072, aborting backtrace.
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
