Have you tried sorting this list alphabetically? Believe it or not,
when I tried to use Apache 1.3.x with PHP 5.2.x with extensions in
arbitrary order I got inexplicable crashes, too.

Ah, stuff like "apache-ssl init's the SSL library, then php + ssl
init's the SSL library, and stuff gets funny."

Right. It has probably to do with some linking and initialization details of the dynamic libraries involved. However, in my case the offending interaction seemed to be just between the PHP extension modules. To fix the problem I didn't have to change the load order of the Apache modules.

Since then I have a line in my PHP upgrade notes that reminds me of sorting the extension list as a last step. This is certainly a pragmatic approach, but for lack of time I didn't bother getting acquainted with the PHP internals, and those of the libs involved, to find the root cause.
