Previous Comments: ------------------------------------------------------------------------ [2002-03-18 09:48:01] frerk@meychern.de The Bug #10044 in shm_remove seems to have happened in sem_remove too. An automatic clean up after a request in php 4.1.1 of all acquired semphores does succeed. An explicit clean up with sem_remove() in php as a standalone script fails with a core dump. <?php // semaphore remove bug in standalone php only $channel_id=crc32("This is a test"); $sem_id = sem_get($channel_id,1,0600); print "$sem_id got<br>\n"; sem_acquire($sem_id); print "$sem_id acquired<br>\n"; sem_release($sem_id); print "$sem_id released<br>\n"; sem_remove($sem_id); print "$sem_id removed<br>\n"; //request cleanup dumps core if semaphore is removed ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16144&edit=1
