What does it say in all of those systems in the phpinfo()
output for "Regex Library"?? Safest would be to use
the bundled one in all of them. 

You should also update to PHP 4.0.5 as it has some fixes
regarding regexps.

This script from www.4cm.com works on Win NT 4.0sp6a and Win 2k Server without any 
problem, but fails on two different Red Hat Linux 7.1 machines.  One 7.1 machine is a 
Dell 166mhz with a 48mb of ram, the other is a Dell P3 600mhz with 384mb of ram. All 
machines are using php 4.0.4pl1. The red hat machines installed php at install time, 
server class installation, no mod_php installed (at least that's what rpm -qi mod_php 
said). Apache is compiled with mod_so.c

If i change the $GrabData = eregi(... line to
$GrabData = eregi("$GrabStart(.*)", ... basically taking out the $GrabEnd, the script 
works.  If i replace $GrabStart with $GrabEnd, the script works.

BUT, it will not work if I have both in the expression (on the Red Hat Linux 7.1 
machines).

Why?
