 New Comment:

As I can't reproduce it this bug, I wonder why you insist to use the
ISAPI? There is now a fastcgi interface for II5/6/7 and it works _way_
better than the ISAPI.

Does the crash happen too when you use a simple script (say phpinfo())
and using the same procedure?

yep, this is definitely a vista/php/isapi problem. It happens so
frequently that I think a fix would really help!

I have updated the bug with backtrace and have contacted the assigned
developer directly (and convinced him that there is no extension
involved in the crash).

However, since I am not the originator, I cannot change the Status.
Please change the status.
Thanks!

"- Use FastCGI rather than ISAPI"

that's definitively the way to go :)

To help people with this issue, I've scanned all the PHP bugs relating
to this issue and collated a list of workarounds:
- Add w3wp.exe to DEP exclusion list 
- Turn off process recycling
- Use FastCGI rather than ISAPI

To the PHP team - you guys are great and I love your work. I know you
haven't gotten the backtrace, but please don't mark this bug as bogus. 
The community is trying to get what you need and have been very patient
with this issue, but it appears to be difficult to get  because of the
way it crashes.
