noexcept operator outside function header

[jt (jt-9)]

Why does msvc compiler fails to compile LWG 4324 test, while gcc and clang do? godbolt example

Tested on cl version 19.51.36243 for x64 fails with following errors
error C2753: 'nothrow_dereference<T,noexcept'function'>': partial specialization cannot match argument list for primary template
error C2338: static assertion failed: 'nothrow_dereference<std::unique_ptr>::value'

Thank you

This is a compiler bug and can be reduced to a library-free repro. Can you file it on VS Developer Community? (Externally-submitted bugs carry more weight than ones I file myself.)

Yes, will do. Thank you
