On HEAD this doesn't fail any longer because of the:
* final.c (output_addr_const): Do not call mark_referenced.
change (part of tree profiling branch merge).

I don't think you can construct a C testcase for this, as soon as you save
some function's address into some reachable variable or take it in
some reachable function, cgraph will know about it.  The OBJ_TYPE_REF is special
in that there is no such variable in the current translation unit
and cp_fold_obj_type_ref just knows what is in the variable (vtable) in
some other translation unit and optimizes that access.

Of course we can
I'm ATM testing 2 different patches, will attach them here once the testing
finishes.
