Description:
------------
Hi.

I'm trying to use PHP to find out about the COM interface of Crystal Reports XI.

I can use ...

php -r "ReflectionClass::export('COM');"

which shows the empty 'COM' class extending the 'variant' class.

But if I try and use ...

php -r "ReflectionObject::export(New COM('CrystalReports11.ObjectFactory.1'));"

I get a crash and a request to send a report to Microsoft.

Reproduce code:
---------------
<?php
$o_CR = New COM('CrystalReports11.ObjectFactory.1');
ReflectionObject::export($o_CR);


Expected result:
----------------
A dump of the properties/methods provided by the Crystal Reports XI Object Factory.

Actual result:
--------------
A crash and a Dr. Watson crash.

I forgot to mention that the function com_print_typeinfo() does provide some of the information I'm expecting to be available via Reflection.

Hmm.

Ok. So no crash, but no valid output either.
