--- Comment #35 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I've backported the std::allocator_traits<std::allocator<T>> partial
specialization to the gcc-4.9 and gcc-5 branches now. Please let me know if
this makes any difference for your use cases (and provide testcases to
reproduce problems if not).
