--- Comment #11 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Hmm, I think this might be not the thing wanted here. But infact having a
VAR_DECL can be caused by prior errors introducing them. So we might simple
want to treat VAR_DECL in unify via unify_template_argument_mismatch.

* pt.c (unify): Don't ICE on VAR_DECL.
Regression tested on x86_64-w64-mingw32. Ok for apply?
