The bug ist reproducible here on Debian Woody + apache-1.3.29/php >= 4.3.4RC3, too. It was most probably introduced while fixing http://bugs.php.net/bug.php?id=26407: sybase_free_result() works properly up to php-4.3.4RC2, but not with a patched 4.3.4RC2 to solve bug #26407 (that patch then made it into 4.3.4RC3). Well, I'm sorry for not testing sybase_free_result() afterwards, never used it before... Best regards, Thomas ------------------------------------------------------------------------ [2004-04-01 15:59:18] deanb at gbtn dot net Description: ------------ If I use sybase_free_result() in a script, then php crashes.
