Can't reproduce this on Linux with 4.4 and 5.1 give all no errors with
valgrind.
PHP 5.0 gives the following valgrind errors:

Reproducible on Windows.

Works fine on Linux.
Still crashes on Windows, even using the snapshot you provided.
------------------------------------------------------------------------
[2005-05-14 12:40:38] tony2001@php.net
Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
Can't reproduce it on Linux with latest CVS of 5.0 & 5.1 without
debug.
Make sure that you're trying the right binary.
------------------------------------------------------------------------
[2005-05-11 11:44:10] shulmanb at il dot ibm dot com
Tested with the latest snapshot (200505110630) on Windows XP, and it is
still crashing.
