 New Comment:

Since we don't fix bugs in 5.3, could you try to see if 5.4 or later segfaults.

The core dumps with the "zend_hash_find" problem occure when APC is disabled. 
With APC enabled, we find "zend_vm_stack_alloc" in the core dumps.

Does this also happen without APC? Any chance to get som ereproduce code? hard 
to identify otherwise.

Disabling APC does not solve the Problem. In both php 5.3. and 5.4 we still 
receive core dumps like this:

zend_hash_find is quite a short function, so it should not be so difficult to 
find the reason for this annoying instability...

Compiled the latest APC version (3.1.13), but same behaviour:
- core dumps with
fe256d98 zend_vm_stack_alloc (1040, ffbff478, fe222de8, 0, 0, 0) + 110
- Service brought to maintenance modus every now and than.

As seems to be usual with cases involving APC, try to reproduce it _without_ 
APC.
You might also care to try the latest APC, though most of its fixes are 
probably 
for PHP 5.4.  

Thanks for the report but a testcase is really needed.
