Description:
------------
php crashes since 5.2.x upgrade, tried 5.2.11, 5.2.13, 5.2.14, 5.2.snap

I ca't compile php in debug-mode, as zend optimizer and ioncube will fail.
any other ways to get a better sight of the initial problem?

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.

aeh.. thats a production machine with 500 vhosts from customers.
no idea which script is broken as the error is not fixed to a special website.
(and it is not a bad memory bank)
any other ideas?
