OK, I think I have a new version of the patch that should fix both the
original and the second BUG_ON which you reported.  Unfortunately,
I've not been able to reproduce the BUG_ON, even by downloading gcc
4.5.1, configuring to build just gcc, and then doing a "make install".
I'm not sure what languages you had enabled, or how much memory you
have on your machine, etc., all of which might have made it harder for
me to repro the bug.  Still, I think I now understand what's causing
it.

Can you give this a try and let me know if this fixes things for you?
