--- Comment #17 from Richard Biener <rguenth at gcc dot gnu.org> ---
So the issue here is that modified_type_die does not really handle
address-space qualification but it claims so.  We ICE after we were supposed to
create a new DIE with the qualification but failed to do so.

In fact the rev. in question (r8-4385-ga297ccb52e0c89) does not cause us to
emit any DWARF indicating the address-space (such thing doesn't exist in
DWARF).

Unfortunately the rev didn't add a testcase.

I'm testing partial reversion.
