If I use an unmodified php.ini it also works partly. It just crashes
after processed the PHP Script. But using the PDO extension it causes to
the crash mentioned in my first post.

If you mean this:
http://snaps.php.net/win32/php5.3-dbgpack-win32-200807280430.zip
- yes

I tried it without any php.ini loaded and it works! At least partly. It
processed the PHP Script and also gave me an output now. But after that
it crashes.

I made an backtrace of this crash. Here the complete backtrace result.
I hope it helps:

I have 4GB Ram :)

Did you have the debug stuff installed when you did that backtrace?
And as it seems this error is caused either by "Out of memory" or when
exceeding memory_limit, try without any php.ini loaded. (just remove
every php*.ini file from your system to be absolutely sure!)

> Does this happen with Apache?
I tried Apache. But Apache does not work for me at all (not because of
PHP) and I have currently no time to try to fix Apache. I am sorry.
Maybe I try it later again ...

But here are my cgi/fastcgi related php.ini options:
cgi.force_redirect = 0
cgi.fix_pathinfo = 1
fastcgi.impersonate = 1

Does this happen with Apache? (Please try) And please provide the
cgi/fastcgi related php.ini options you have used.
