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.

>>>>>  graphunixx11.c, line 3191

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

	mutex =3D (pthread_mutex_t *)vmutex;
	pthread_mutex_unlock(mutex);
#else
	mutex_t *mutexid;

	mutexid =3D (mutex_t *)vmutex;
	mutex_unlock(mutexid);
#endif
}

Apparently, if I remove function pthread_mutex_unlock() : it runs.=20
But I don't think that is good to remove the function
pthread_unlock_mutex.


Any proposals ?
