It's not an ICE on x86, but the dump shows the incorrect pointer type.
Can I assert that the cand_type is a pointer and not a reference?

--- Comment #4 from Stefan M Freudenberger ---
I guess there wouldn't be an issue if it were a reference type. However, there
is an issue with the incorrect alignment for the object type.
