... actually adding Jason to the CC list ;)

I've marked the other as a dup after comparing the results for both testcases
with G++ 4.4 and later versions.

Jason, is this likely to be easy to fix?  I've been hitting this and PR 47335
while implementing std::allocator_traits.  If they aren't likely to be fixed in
the near future I'll look into workarounds
