[1091] does not fix the reported problem. The issue is that pthread_mutexattr_init and pthread_mutexattr_destroy aren't used on the pthread_mutexattr_t structure in PosixMutex::PosixMutex?() causing pthread_mutexattr_settype and pthread_mutex_init to have undefined behavior. See the attached patch for details.
