Comment 6 for bug 693387

I don't know how to proceed without a stack trace or similar info about where exactly the mysqld binary is crashing.

To get a core file you may need to add --core-file option to my.cnf and/or make sure `ulimit -c unlimited` is active for mysqld. You may also need to ensure that mysqld has write permissions to current directory (or wherever FreeBSD puts core files, this is somewhat system dependent AFAIK).

Alternatively, start mysqld by itself (without using mysqld_safe) from within gdb, giving the same arguments that mysqld_safe would pass. This should also provide a stack trace.
