--- Comment #13 from Martin Sebor <msebor at gcc dot gnu.org> ---
Reconfirming as still failing with today's top of trunk (6.0), plus 5.x and
4.9.3. I get the following stack trace on the small test case from comment #4:
z.c:18:43: in constexpr expansion of
‘BitsOrderCheck().BitsOrderCheck::IsLsbBottom()’
z.c:18:54: internal compiler error: in cxx_eval_bit_field_ref, at
cp/constexpr.c:2095
static_assert(BitsOrderCheck().IsLsbBottom(), "blah");
