crash dump on OS X Server: PHP / Apache

Perhaps someone can read this backtrace. This is a problem that causes Apache to not send any output at all. Doing a die() just before one particular require_once prevents the issue. If I move that die() into the required file and place it just after the opening PHP tag, I get the error again. I have verified the PHP syntax of this file with php -l . This site uses CodeIgniter and FileMaker's PHP API, and the include file where this happens is one of the API files. The PHP library is the one supplied by FileMaker 12 Advanced Server. Another PHP application on the same server, using the same FileMaker API is running just fine, but that one isn't using CodeIgniter. Any insight would be greatly appreciated. Mattias
