--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, but there's no local variable to copy here?  Are you refering to the
result decl from b we materialize in c?  This would be the same case
as for example switch conversion adding a 'long long' variable, so the
issue would be more wide-spread as you think - for example IPA SRA might
choose to pass an aggregate by its components thus with an aggregate with
two long long members you should see similar issues.
