libstdc++: Missing 'constexpr' in vector's from_range ctor [PR119282]
A missing 'constexpr' in the non-forward (and non-sized) branch of our
recently implemented vector from_range ctor was causing this valid example
to be rejected with a cryptic error.
PR libstdc++/119282
libstdc++-v3/ChangeLog:
* include/bits/stl_vector.h (vector::vector(from_range_t)): Add
missing 'constexpr' to local class _Clear.
* testsuite/std/ranges/conv/1.cc (test_pr119282): New test.
