and tested in PHP 5.2.8. Problem still occurs.

Small question along the lines, is this true:

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read

http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug

us make PHP better.

A backtrace would help us since we can't seem to reproduce this on Linux or OS X.
