Yes, I think this one is too.

Bug 99059 is similar (involving C++17 "inline" rather than constexpr) and
Jonathan Wakely said it's a bug.

I believe it's valid because the point of declaration of a variable is just
before its initializer
(https://timsong-cpp.github.io/cppwp/n4861/basic.scope.pdecl#1), and thus the
variable should be in scope in its initializer.

But I'm not a wording expert and it's possible I'm mistaken, or overlooking
something else that would make this invalid.

ICC and MSVC reject it similar to GCC even.  Are you sure this is valid?
