That's an odd one for sure. An easy workaround would be to stick to the
mapserv CGI that works and forget about the broken one. There is no link
at all between the mapserv CGI and your PHP at runtime, so you can use
any mapserv CGI with any PHP on your server.

Now, it would still be good to know why this happens and fix the issue
if it's in MapServer. Are your two PHP source trees configured and
compiled with exactly the same options? Perhaps you could do an 'ldd
mapserv' with both versions and see if different libraries end up being
picked up. The real way to figure this out would be to use gdb and see
where/why the crash happens. If others can confirm that they get the
same problems with PHP 5.0.3 then please create a bug with your
configuration information (PHP and mapserver configure options, OS,
etc.) and I'll see if I can reproduce it.
