Jason, Marek,
it seems that the issue is in build_ref_qualified_type in C++ frontend. It
builds a type variant which is correctly built with tree.c as having same
canonical type as the main variant and then it does:
1972 else
1973 /* T is its own canonical type. */
1974 TYPE_CANONICAL (t) = t;
here we end up with TYPE_CANONICAL being a variant type. This seems odd to me,
but it looks like this code is intentional.
I think the effect of this code is that pointer to TYPE and pointer to T (i.e.
the type and the qualified type we build it from) will be considered
incompatible. So it seemt o me that hunk should be dropped?
