--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> --- ... and the issue is one more level deeper, because __is_trivial just uses the internal trivial_type_p. I mean, it should be pretty easy to construct testcases not involving __is_trival at all but handled incorrectly: outside the implementation of the intrinsics, the internal pod_type_p itself is, predictably, std_layout_type_p && trivial_type_p and then anything depending on POD-ness is sensitive.
