URGENT - I found the bug...?!

Hi!

If I'm performing:

TMyGraphicOutDevice(OutDevice).GraphicReport := GR;

....but, OutDevice is a TMyDotOutDevice and not a TMyGraphicOutDevice
instance. The GraphicReport property doesn't exists at TMyDotOutDevice
class!!!

Can this typecast raise an "internal exception" that crash my application
closing without a message error?

Tks!!!!!
