I had updated to:
PHP 4.3.3
Apache 2.0.47 (Win)

The problem still remain. I saved the temp files that WinXP has created during crash. It can be found at:

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at
In case this was a documentation problem, the fix will show up soon at

In case this was a website problem, the change will show
up on the site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.

The crash was caused by the fact that 'wddx' serializer handler was not enabled in the build. Any unknown serializer would cause the crash. I have fixed both the cause (missing wddx handler) and the symptom (crash) in CVS.

I had updated with PHP 4.3.4-dev from (file, but the bus still remain.

You didn't install it correctly. Remove all old php related dlls from your system (everywhere!) and reinstall the _latest_ STABLE snapshot.

Done! I had some php related dlls in c:\windows\system32 folder. Now it's OK.
