Description:
------------
When running the code found below, PHP seems to choke in recursions.
Naturally, the code itself is flawed; but this flaw should not be
capable of segfaulting PHP. This can be seen as both a security and a
stability flaw.
Reproduce code:
---------------
<?
function foo($bar) {
if(is_array($bar))
foreach($bar as $k => $v)
print $k." => ".foo($v);
else
var_export($bar);
}
foo($GLOBALS);
?>
Expected result:
----------------
Fatal error: Nesting level too deep - recursive dependency?
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
