Description:
------------
The following code crashes my install of PHP from July 13, 2003.
Removing the class hint in BoomWalker eliminates the crash.
Reproduce code:
---------------
class SomeClass {}
class CrashClass {
function Boom()
{
$a = array( 0,1,2 );
array_walk(&$a, "BoomWalker", &$this);
}
}
function BoomWalker(SomeClass &$arrayItem, &$key, &$crashObj) {}
$c = new CrashClass;
$c->Boom();
Expected result:
----------------
Nothing.
Actual result:
--------------
System alert for PHP crashing.
