Edit report at https://bugs.php.net/bug.php?id=71764&edit=1 ID: 71764 Comment by: sking at psc dot ac dot uk Reported by: sking at psc dot ac dot uk Summary: LDAP and PDO_OCI causing segfault in Apache Status: Open Type: Bug Package: Reproducible crash Operating System: SLES 11 PHP Version: 7.0.4 Block user comment: N Private report: N New Comment: And the annoying thing is that I've been running a server with PHP compiled with debug mode enabled for a few weeks now and it won't crash. As soon as I disable debug mode, it will crash within a day or two. It's proving tricky to get more information on this bug.

In my case before graceful restart: Compiled Version => 1.2.7 Linked Version => 1.2.7 After graceful restart: Compiled Version => 1.2.7 Linked Version => 1.2.3.f-ora-v2 ------------------------------------------------------------------------ [2016-08-10 09:18:21] requinix@php.net @ere: That code has nothing to do with this.

I can reproduce on CentOS 7 with PHP 7.0.9 and Apache 2.4.6 with the following script: ----------------- <?php header('Content-Type: image/png'); $img = imagecreatetruecolor(100, 100); imagepng($img); ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
