Anyway, that's expected behaviour as stated in other bug reports.

You should first try hard to crash it with that tiny script.
If it really was to go wrong, then reopen this bug to let us know what
did actually happen on your server :)

i know, (mistake from me ;-).
But now the problem is that i can crash the server if i want by making
an endless loop (with calls).

function crash(&$test) {
if ($test < 10)
crash($test);
$test++;
}
There's no chance $test is incremented. So no matter how the variable
is passed to the function, it will definitely go into an infinite loop
and end up eating up all the stack area which really causes
segmentation fault.
