--- Comment #3 from John T. Criswell <criswell at uiuc.edu> 2010-04-14 15:31:31 CDT ---
I believe you are correct in that the two GEPs exhibit equivalent behavior on a
64-bit target (the result pointer is 8 bytes less than the source pointer). 
Furthermore, each GEP indexes the pointer out of the bounds of a valid memory
object, so both are equally incorrect.

I'm marking the bug resolved and invalid.

Thanks.
