Bug #16905 Updated: mkdir crashes

ID: 16905 Updated by: jimw@php.net Reported By: mav@alkar.net -Status: Feedback +Status: Closed Bug Type: Scripting Engine problem Operating System: FreeBSD 4.5 PHP Version: 4.2.0 New Comment: This bug has been fixed in CVS. You can grab a snapshot of the CVS version at http://snaps.php.net/ fix was merged into 4.2 branch, so it should be included in 4.2.1. (we were passing a pointer to a mode_t, which is a short on freebsd, and it was being treated elsewhere as a pointer to a long. this is the fun sort of bug that usually only shows up on non-debug builds.) Previous Comments: ------------------------------------------------------------------------ [2002-05-06 11:37:39] kalowsky@php.net Happens in 4.2.1RC1 as well. When compiled with --enable-debug, works fine. When compiled with --disable-debug, it doesn't work ------------------------------------------------------------------------ [2002-05-02 06:04:48] jason@jase.org Just to further confuse the issue. If I build the 4.3.0-DEV snaphost (php4-200205020000) with --enable-debug then it behaves normally. Jason ------------------------------------------------------------------------ [2002-05-02 04:54:10] jason@jase.org I've just tried a 4.3.0 snapshot using the same test file as mav@alkar.net posted above. Operating system is FreeBSD 4.5. ----------------------------------------------------- php4-200205020000# ./php ~/test.php X-Powered-By: PHP/4.3.0-dev Content-type: text/html <br /> <b>Warning</b>: mkdir() failed (No such file or directory) in <b>/disk1/home/jase/bigmailbox/test.php</b> on line <b>3</b><br /> Segmentation fault (core dumped) ------------------------------------------------------------------------ [2002-04-29 16:16:53] sniper@php.net I can not reproduce this with PHP 4.3.0.
