Hi,
I reported this bug and noticed that it is already reported.
http://bugs.php.net/bug.php?id=47689
Hence it is a php bug which will be removed in future versions.
But thanks for fast answer.
Kind Regards
Bananen-Joe

Not compared to the thousands of characters some people fling at PCRE. :-)
I am not a PHP user; from what you posted, I am not sure that I
extracted the final string that would be passed to PCRE.

I deal only with PCRE; I don't know or use apache or php. I have tried
to run the match directly using pcretest, but as I said above, I am not
at all sure I had the right data. Combination errors usually need the
attention of the most downstream maintainer - in this case, probably
PHP. Have you reported this to the PHP people? If you can provide a
pattern and a data string that cause PCRE to misbehave in some way, then
I will certainly look at it.
