New Comment:
What loop??
Remove the "global $moo" and the $rar = 0 and it runs as expected:
<?
switch($t)
{
default:
function segfault()
{
echo 'About to segfault : ';
}
segfault();
}
echo 'Or not. Look no loop.';
?>

?
You call the function segfault() in a never ending loop.

There is no recursion. This is a function being called from within a
switch block. Surely?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This is expected, PHP does not protect against infinite recursion.

Description:
------------
I've tried to get the code to the minimum required to cause a crash.
The combination of the local variable being defined and the global
reference seems to be causing stack corruption (the script never
returns successfully from the function call:
jelly can # php -f crash.php
About to segfault : Segmentation fault
jelly can # php -v
PHP 5.0.1 (cli) (built: Aug 18 2004 12:39:38)
Reproduce code:
---------------
<?
switch($t)
{
default:
$rar = 0;
function segfault()
{
global $moo;
echo 'About to segfault : ';
}
segfault();
}
?>
Expected result:
----------------
About to segfault :
Actual result:
--------------
About to segfault : Segmentation fault
