This is from a PHP binary built with the 4.3.2RC2 source. I have created a working CGI binary by rolling back to the 4.3.1 source. This problem seems to be new in 4.3.2 thread.

Remove Zend Optimizer.. 
Does that solve it ?
 [2003-05-05 21:22 UTC] dave at socrates dot thinkhost dot com 
Nope, I have commented out the Zend Optimizer lines in the PHP CGI php.ini, it makes no difference. Note that I have also tried building a basic PHP CGI binary (./configure --disable-all)

This problem is the same problem as bug report #23196 (which was never solved, and started with the PHP-4.3.2RC1 source tree)
 [2003-05-05 23:13 UTC] magnus@php.net 
Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.

ok then.. Add your comments to #23196 .
