IMO it should not segfault at all, but have you noticed that the
'file' you are actually trying to read is "/\'{1,}(([^'])+)\'{1,}/ie"
and not testfile.txt?

By the way:

$ php --version
PHP 5.2.0-8+etch10 (cli) (built: Jan 18 2008 18:52:58)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2006 Zend Technologies

$ php t "/\'{1,}(([^'])+)\'{1,}/ie" "TEST" testfile.txt

Warning: file(/\'{1,}(([^'])+)\'{1,}/ie): failed to open stream: No
such file or directory in /root/t on line 3

Warning: implode(): Bad arguments. in /root/t on line 3
== Original:

Warning: preg_replace(): Delimiter must not be alphanumeric or
backslash in /root/t on line 5
== Replaced:


Same result when trying on 5.2.5-3.
