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.

Now, of course it was just a coincidence that it worked for me after 
sorting the extension list.  What this in fact points to is that the 
order of extensions can be important in that list, for whatever reason. 
  For me it worked after sorting the list, but YMMV.  Might be worth a 
try, though.
