--- Comment #6 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Yes, delayed folding fixes wrong-code/valid-code samples.

For invalid-code I see with delayed folding the following error-messages:

t_pr57335.C: In function 'int main()':
t_pr57335.C:29:5: error: non-constant condition for static assertion
     static_assert(BitsOrderCheck().IsLsbBottom(), "blah");
     ^
t_pr57335.C:29:47:   in constexpr expansion of
'BitsOrderCheck().BitsOrderCheck::IsLsbBottom()'
t_pr57335.C:29:5: error: accessing 'BitsOrderCheck::Data::bits' member instead
of initialized 'BitsOrderCheck::Data::byte' member in constant expression

Not sure if this is desired.
