Bug description:  Any script containing a parse_ini_file() call results in a segmentation fa
ult

Any script that contains a call to the parse_ini_file() function results in
a segmentation fault. This is the case for mod_php4 and the CLI. The
scripts used to test this are at
http://jodrell.net/files/parse_ini_file_bug/

Here's what happens when the script is run from a shell:

[root@spoon rael]# /usr/local/bin/php parse_ini_file_demo.php 
Date: Tue, 20 May 2003 10:37:09 +0100
This string is printed before parsing.
Segmentation fault (core dumped)
