I reported this bug ( id : pkg/35261 ) and prevent the maintainer.

The source of problem is into the graphunixx11.c file from
electric/src/graph/ directory.

/*
 * Routine that unlocks mutual-exclusion object "vmutex".
 */
void emutexunlock(void *vmutex)
{
#ifdef HAVE_PTHREAD
        pthread_mutex_t *mutex;

        mutex = (pthread_mutex_t *)vmutex;
        pthread_mutex_unlock(mutex);
#else
        mutex_t *mutexid;

        mutexid = (mutex_t *)vmutex;
        mutex_unlock(mutexid);
#endif
}

<<<<<

Apparently, if I remove function pthread_mutex_unlock() : it runs. 
But I don't think that is good to remove the function
pthread_unlock_mutex.


Any proposals ?
