Do you have a mix of modules that are both multi-threaded and
single-threaded loaded in Apache?

I'm not sure what else could be a root cause for this particularly nasty
problem.

Running apache_1.3.37 with php5 (about as generic as I can get). Here is
the php extensions.ini file:

extension=ctype.so
extension=dom.so
extension=ftp.so
extension=gd.so
extension=gettext.so
extension=iconv.so
extension=pcre.so
extension=zlib.so
extension=pdo.so
extension=posix.so
extension=session.so
extension=simplexml.so
extension=sqlite.so
extension=tokenizer.so
extension=xml.so
extension=xmlreader.so
extension=xmlwriter.so
extension=mysql.so
extension=imap.so
extension=sockets.so

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.
