Here's a very simple test case to reproduce this bug:
<?php
function crash($data) {
crash(1);
}
crash(1);
?>

Description:
------------
I know this bug has been reported as "Bug #18909: Stack overflow error"
but I think this should be fixed and not treated as bogus like in bug
#18909.
Scripting engines should _never_ segfault!
A stack overflow in a recursive php-function leads the php-engine to a
segmentation fault.
There is a second issue that could be in associated with this one. If a
function is called very often (sometimes recoursive - depth not greater
than 20) php crashes too. We've not investigated this issue further
enough to write a script to reproduce this behaviour.
Reproduce code:
---------------
<?
function MyTest($A, $B, $C, $D, $E, $F, $G)
{
for ($k=0; $k<100; $k++)
{
echo "|".$A++."|<BR>";
flush();
MyTest($A, "", "", "", "", "", "");
}
}
MyTest(0,"","","","","","");
?>
Expected result:
----------------
A php error complaining about a stack overflow.
Actual result:
--------------
[notice] child pid 29029 exit signal Segmentation fault (11)
