Uh, not really - in debug mode it simply does not return anything, 
blocking the caller.

("RET" is "\n" typed by me.)

> telnet localhost 80 RET
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /unidsl/udgate_scripte/wnet_cgi/cgi/rueckmeld.psp HTTP/0.9 RET
RET
(Here it hangs.)

In contrast, if I run "a2dismod php5" and restart Apache:

> telnet localhost 80 RET
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /unidsl/udgate_scripte/wnet_cgi/cgi/rueckmeld.psp HTTP/0.9 RET

In standard mode, Apache doesn't crash, it just returns empty documents. 
Only parsestring() causes a SIGSEGV, I'll write a tiny test script soon.

Both logs are attached.
