I couldn't isolate the code yet. However the full backtrace is the
following (I ran the same app twice):
1st time:

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.

This snapshot is identical to the one I tested as far as I am seeing
comparing the 2 archives, however which files did you modify?
The only way I have to trigger this bug is recompiling the engine on a
production server but since it breaks several websites (Drupal seems to
be most affected) I can do it only at night so I can perform a limited
number of attempts.

Please try using this CVS snapshot:
http://snaps.php.net/php4-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-STABLE-latest.zip
sorry, can you please try again a new snapshot? I made some changes a
few hours ago and I don't know if they made their way in the snapshot
you tested.
If it still doesn't work, please post the entire backtrace (or link to
an external page if it's too big). Also please try to isolate the code
that triggers the bug.

I compiled CVS 200702251930 but unfortunately the problem persists.
