#!/usr/local/bin/php -q
<?
shm_attach(1234, 1000, 0600);
?>
to reproduce bug you should first start this script as user A. then, login as user B
and start it again.
i noticed that 4.0.5RC5 has no segfault at this point.
instead, correct message appears:
<br>
<b>Warning</b>: shmget() failed for key 0x4d2: Permission denied in <b>./test.php</b>
on line <b>2</b><br>
so, i think this bug is closed.

Could you provide a small sample script (just enough code for this to fail.) for us to
analyze?

got segfault using shm_attach():
1) script started as user A creating shared memory block: shm_attach($mem_id,
$mem_size, 0600);
2) same script, but started as user B trying shm_attach($mem_id, $mem_size, 0600);
(it cannot be done, because access rights is 0600 - memory is for owner only)
the result is segmentation fault.
