#18930 [Opn->Csd]: foreach() causes httpd child to segfault

ID: 18930 Updated by: iliaa@php.net Reported By: tolli@tol.li -Status: Open +Status: Closed Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 4.2.2 New Comment: This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. The crash is gone. The remaining memory leaks are the result of a recursive reference to the $s variable.
