Do you run the Non-Thread-Safe version of the PHP and Xdebug as advised on the IIS site ?
Are there any errors when you run the php.exe from cmd prompt ?

If you can provide a snippet of PHP code that you try to run would be great.
Or does it happen regardless of code you try to run ?

it happens regardless of code. it just most of the time does crash if xdebug extension is loaded.

i don't know what else i can provide for you to easier trace back the problem,
if you do please let me know.

I have exactly the same issue with apache 2.2 and PHP 5.2.17 on Windows 7 (64Bit).
If I start the apache and load the first PHP script (maybe phpinfo()) a fatal error occurs with ntdll.dll error information.
I've tried TS with apache PHP module and NTS with FGCI allways the same problem.
Only if I use the xdebug version 2.1.2 (VC6) the issue doesn't occur.
On all VC9 versions the issue exists!

With the latest versions of PHP (7.0) and Xdebug (2.4.x), does this still cause a problem for you?

it's no longer relevant for me personaly, as we migrated away from IIS and PHP 5.2, to apache with php 5.5
