At first, I should say sorry for easy type miss :(
I meant "PHP crash".

I tried other codes to find out the pattern of this problem.
<?
class bug {
function get(bug $bug)
{
return $bug;
}
}

class test {
function call()
{
$bug = new bug;

// PHP should report the missing argument here
$bug->get();
}
}

$test = new test;
$test->call();
?>

This code also cause PHP crash like the reproduce code I posted
before.

=============================================
Apache.exe - Application Error
Command "0x100f334" tried to refer Memory "0x0000000c".
Memory could not be "read"

Nonhandled Exception occurred in Apache(PHP4TS.dll)
0xC0000005: Access Violation
=============================================

but, I am not sure why this problem happen...
I hope other users can reproduce same problem so that more infomation
will be available for this problem...
