You can access the patch from: http://lists.mysql.com/commits/73585 3136 Marc Alff 2009-05-07 Bug#44710 assertion failure in mdl when server starts, related to performance schema The assert was related to a build warning. THR_LOCK_mutex is pthread_mutex_t, not a mysql_mutex_t. Using thread_safe_increment caused the code to use a non existent m_psi pointer. Fixed another build warning (bytes may not be initialized).
