Description:
------------
The staring point is a compiled custom class, which extends some php built in class.

If I call a method on the custom-class which is defined within the parent class i got a seg fault.

Reproduce code:
---------------
Compile-Code:

$f = fopen('compile/MyClass.php', "w");
bcompiler_write_header($f);
bcompiler_write_file($f, 'MyClass.php');
bcompiler_write_footer($f);
fclose($f);

MyClass.php:
<?php
class MyClass extends DateTime {
}
?>

Calling script (index.php):
<?php
require_once 'MyClass.php';

$o = new MyClass();
$o->getOffset();
?>



Expected result:
----------------
The offset of DateTime

Actual result:
--------------
$ php index.php 
Segmentation fault
Exit 139
