--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
I should note that attribute aligned is accepted with larger values than 128,
so the problem is limited to enforcing the limit requested via the C++ 11
alignas operator. As evident from the number of bugs linked to bug 58601,
alignas and its interaction with attribute aligned suffers from many problems
in G++.
While the x86_64 back end might be confused about some of the alignment macros
I think the underlying problem here is thec
heck_cxx_fundamental_alignment_constraints() function and its use of the
macros.
