--- Comment #5 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-06-28 09:59:40 UTC ---
Confirmed.  There is nothing invalid here, you can take the address of
such variable - you just cannot inspect it.  Of course that is what
inlining exposes here (and via MEM_REF we get to see the external decl).

Hmhm.

I'll look at it.
