I know this might sound dumb, but do you have any stack size limits in

How about a backtrace? (Jani?)
Is it PHP or PCRE that's causing this problem?
------------------------------------------------------------------------
[2002-09-20 07:21:16] [EMAIL PROTECTED]
I still can reproduce it with latest CVS HEAD and RH 6.2/x86
------------------------------------------------------------------------
[2002-09-20 04:45:55] [EMAIL PROTECTED]
I cannot reproduce this bug using the latest cvs on redhat 7.3. The
script just keeps going. I cut it off after 20000 chars.
I also do not experience this problem with the latest cvs release on
FreeBSD 4.6-STABLE.

I've reproduced this using the php4-win32-latest snapshot.
The only difference is that it crashes at
char 3915 instead of 4041. Sorry, but not gdb hence no
backtrace.
