The remaining issue to be discussed is what to do about that old bug, c++/27952, a crash in decay_conversion during error recovery, when vtt is found null. I propose to simply check for it in build_special_member_call, avoid passing an unusable null argument to decay_conversion and return back an error_mark_node. We could also do gcc_assert (seen_error()) before returning error_mark_node?
Why is vtt null? Jason
