@EricWF

What do you mean?

The change is correct.

You mean gcc and clang compiler frontends have bugs?

By the way libstdc++ has the static_assert since Nov 13, 2009 (https://github.com/gcc-mirror/gcc/commit/7274deff738213914a31413a9d1a671020694175)

I see that MSVC works with that example: https://gcc.godbolt.org/z/cjE8dard7

However it has the same library implementation...
