PHP 4.0 Bug #10115 Updated: segmentation fault

ID: 10115 User Update by: root@anight.org Old-Status: Feedback Status: Open Bug Type: Semaphore related Description: segmentation fault #!/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.

Sean --------------------------------------------------------------------------- [2001-04-02 09:23:43] root@anight.org 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.
