Core files from apache/PHP without -X

Hi all, I need someone's help. I am trying desperately to find a segfault bug in PHP's output compression. I can not make it happen on a test server as it is just me hitting the site and what I do doesn't cause a segfault. So running it in gdb doesn't work. And using the httpd -X option to create a core file does not work for the same reason. I can, however, for the purpose of finding this bug, run a debug version of PHP on a production site for 3 minutes to get dozens of segfaults (I'll consider it downtime as the server load will pass over 350). But apache only creates a core file with the -X option. So I am stuck with either having lots of people hit it and cause the bug, but not be able to debug, or I can debug but not ever come across the bug I'm looking for. So is there any way to force Apache to dump core files? TIA -steve-
