Hello.

runkit_method_redefine() doesn't want to work for me and cause php crashing.

Thanks for your reply.

Reproduce code:
---------------
<?php
function testme() {
  echo "Original Testme Implementation\n";
}
testme();
runkit_method_redefine('main', 'testme','','echo "New Testme Implementation\n";');
testme();
?> 

Expected result:
----------------
Original Testme Implementation
New Testme Implementation

Actual result:
--------------
Original Testme Implementation

Here is the backtrace:
