Mike's correct.  Nothing you can do in PHP will segfault the Apache
PHP module or Apache itself unless there's something broken in either
php or apache.

You could do things that will generate a fatal error in php, but
that's what php would report in the apache error log...not a segfault.

It may be some broken feature/function in php that's happening to get
called in the recordings page.
