Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Just to be on the safe side..try the PHP 4 snapshot too.

Sniper, you either have finely tuned searching skills or the memory of
an elephant (or both).  It would appear that this is either a duplicate
or very similar to the straggly named bug #17772.

As you requested, I tested the problem with following versions:

4.4.0 - Broken
5.0.5 - Broken
5.1 RC1 - Good
5.1 CVS - Good

I'm not sure what changed between 5.0.5 and 5.1 RC1 that could fix this
problem.  Perhaps someone who's more familiar with the sources can shed
some light.

Currently, I'm looking to solve this for 4.4.0 because upgrading to
PHP5 is not an option for our project.

Thanks for all the help!

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

And don't try to outsmart the configure with any CFLAGS or LDFLAGS of
your own.

See also bug #17772 which has some talk about optimizations and some
other options.
