Bug description:
System V semaphores don't work.

Solution:
This bug is in sysvsem.c file
look at lines near 273:
/* This is correct for Solaris 2.6 which does not have union semun. */
if (semctl(semid, SYSVSEM_SEM, SETVAL, &max_acquire) == -1) {
php3_error(E_WARNING, "semctl(SETVAL) failed for key 0x%x: %s", key, strerror(errno));
}

must be not "&max_acquire" but "max_acquire"!!!
the correct line is:
if (semctl(semid, SYSVSEM_SEM, SETVAL, max_acquire) == -1)
