Description:
------------
I was running an XP (SP3) machine and started having this problem. I installed Vista instead (SP2 RC), but the error occurred almost immediately. It only appears to be while our site is running on this machine, but it is always reproducable, and occurs for the localhost, or remote hosts. I get this error first, repeatedly:

PHP has encountered an Access Violation at 00838493 (on XP, I think it was a different number, but always the same number repeatedly.)

Then I get a 500 Internal Error.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

After further testing, it appears to be xDebug that cause this. Even when not debugging, but if it is even loaded via php.ini. As far as sample code, that's hard to do. It doesn't happen on simple code, but only on my very complex applications.

Please report it to the xdebug project. There is also an upcoming release there which may fix that.
