Description:
------------
I could use some help trying to isolate this crashing bug. Seems like it is stuck in a loop.

Reproduce code:
---------------
I have PHP compiled with --enable-debug and both it and apache are compiled with '-g' option to CFLAGS. Should I not get a better backtrace?

Expected result:
----------------
no crashes. Sigh.

Actual result:
--------------
