We got a workaround for it in PHP5, but we're not going to add it to
PHP4, so you have to upgrade your PHP first.
This issue (if it's really what it seems to be) is actually not PHP
problem, but a well-known PCRE issue.
Though, I wouldn't be 100% sure without a test-case.

Is this issue going to be fixed in the next release? Unfortunately it
breaks lots of things, including very popular apps. I will try to do my
best in finding the responsible php code but I'm not sure it will be
possibile.
Thanks for your interest in this matter.

Yup, it does look like a stack overflow (which is a known issue in
PCRE), though we would appreciate a test case anyway.

I couldn't isolate the code yet. However the full backtrace is the
following (I ran the same app twice):

also please post the whole backtrace, so that we can see what's
happening (it may be just a stack overflow..)

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
