This "fix" makes no sense, but it avoids an error from G++ about std::is_constructible being incomplete. The real problem is elsewhere, but this "fixes" the regression for now. libstdc++-v3/ChangeLog: PR libstdc++/96592 * include/std/tuple (_TupleConstraints<true, T...>): Use alternative is_constructible instead of std::is_constructible. * testsuite/20_util/tuple/cons/96592.cc: New test.
