Description:
------------
Apache crashes when calling a php function declared in a case statement and with a global variable.

Reproduce code:
---------------
$a = 1;
switch ($a)
{
    case 1:
        function test ()
        {
            global $plop;
            echo "test $plop";
        }
        $plop = "(bis)";
        test();
        break;
}

Expected result:
----------------
"test (bis)"

Actual result:
--------------
apache crashes.

just move the function outside the switch and it will work.
