--- Comment #7 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Richard, I don't believe this is a dup. According to my git-bisect, this was
fixed or made latent during gcc-6 development by your patch:
https://gcc.gnu.org/ml/gcc-patches/2015-07/msg00120.html
[PATCH] Consolidate alignment folding
(this is r225310 on trunk)
How to go forward from here?
(about the alignment dumping patchlet, I think it would be nice to have this
functionality on trunk, can I help with that? is there something I'm missing
about this patch that makes it unsuitable for trunk as-is?)
