    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.
    Attempting to collect some information that could help diagnose the problem.
    As this is a crash and something is definitely wrong, the information
    collection process might fail.

    key_buffer_size=8388608
    read_buffer_size=131072
    max_used_connections=0
    max_threads=151
    thread_count=0
    connection_count=0
    It is possible that mysqld could use up to
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68215 K  bytes of memory
    Hope that's ok; if not, decrease some variables in the equation.
