How about a backtrace? (Jani?)
Is it PHP or PCRE that's causing this problem?

I still can reproduce it with latest CVS HEAD and RH 6.2/x86

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.

And I can still reproduce it with the short script and using latest
CVS. (which has the new pcre lib)

I didn't see that Jani reproduced this.

FWIW, I can not reproduce using current CVS or with
PHP 4.2.1 (the oldest version I had to hand just now)
using the short script that you provided.
