 New Comment:

Without a debugger we don't know what happens at all. There are at least two 
options:

1.
 - open windbg
 - click file->open executable and point it to httpd.exe, don't forget -X in 
the 
arguments field
 - click debug->go ... i had to do that twice as it haven't found symbols for 
the first 
time. The symbols have to be setup before of course.
At this point it should be crashing inside windbg

2. Setup a debugger for unhandled exceptions, here's the paper 
http://support.microsoft.com/kb/121434 . After this every crash will invoke 
windbg.

Don't give up, you can do it :)

Sorry... the debugger is not going to help here.
There is not enough time to choose your process
and build your rule before it bombs.

How do you start apache? Please do not start as service, use the -X option, 
like 

c:\apache\bin\httpd.exe -X

combining that with WinDbg.

I got the debug pack and Windows Debug 1.2
It will be no help in this case...
You can only debug a running process, a service, or some IIS and COM stuff.
PHP is not visible in the process list long enough to pick it, if at all.
Debugging Apache gave nothing, as it is not crashing,
just detecting PHP failed to start and shutting down.

Here's the path to debug symbols

I do believe the Apache is from the lounge... I wanted the VC9 version.

The dll is there, as evidenced by the fact that command-line PHP runs.

I'll need some help to make a back trace.
Most of the links on http://bugs.php.net/bugs-generating-backtrace-win32.php 
are broken.
Where can the debug pack for 5.4.14 be found?

Here is the Apache log for a normal start on my server:

Not a thing in php_errors.log or system event logs.
