from the bt, I guess, there is memory corruption within Zend engine.
if you are able to reproduce this crash by running a modified version
of
your script from the command line, then , to help us more understand
the
problem, will it be possible for you to run it with valgrind --num-
callers=15 --error-limit=no ./sapi/cli/php <test-script>
alternatively, if you export USE_ZEND_ALLOC=0 in your apachectl script,
your server might run successfully albeit at decreased performance.
thanks for your help

Up till now, I haven't been able to exactly pinpoint the problem. As
mentioned below, our application works as expected, it looks likes
Apache crashes -after- php has compiled the page. Very strange. The
application is quite large, a lot of code. Tried to debug with Zend
Debugger, but than things work as expected, no segfault.
As much as I would like to give some example code, I cannot at this
moment, since I have no clue where things go wrong (the app works
fine!).
Any suggestions on how to proceed are highly appreciated.

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.

I've compiled the snapshot, gives the same segfaults.
