Description:
------------
Today we had an annoying issue with a complex class model, of which two classes happened to call each others method in a never ending loop. The result was a "Segmentation fault" providing no further information about the source of the error. PHP probably should handle those (programming) errors itself providing a more detailed error message.

I could reproduce this error on a Scientific Linux with PHP 5.1.2 (cgi) as well as PHP 5.2.5 (cgi) and on Ubuntu Linux with PHP 5.2.3 (cli).

Reproduce code:

Expected result:
----------------
Actually it really is a programmer's error. But it was really hard to identify because of the annoyingly short message "Segmentation fault". It would even have helped to get a "call stack overflow" instead.

Actual result:
--------------
Segmentation fault
(I did not append a backtrace, because I think the problem is very obvious and I'd hate to compile PHP on a binary-based distribution. If you need it, tell me and I'll try to get you one.)
