When I executed a MYSQL query command, a coredump cames out. But not all the time, it means the program will appear core dump sometimes. Does anybody can tell me why it happens?
The following is the core debug informations.
by the way, I executed the SQL statement in the MYSQL-front directly, no retult returned.
