--- Comment #18 from Paul A. Bristow <pbristow at hetp dot u-net.com> ---
Working on test for Boost.Multiprecision UDTs, I have just stumbled on this,
expecting loopback to 'just work' as it does on Clang libc++ and MSVC.

LWG 2381 is still (currently open) and seems to have stalled?

Is there any way to get this resolved for GCC libstd++?
