PR libstdc++/101599 libstdc++-v3/ChangeLog: * include/bits/ranges_algo.h (__reverse_copy_fn::operator()): Add missing std::move in return statement. (__partition_copy_fn::operator()): Rename templtae parameter _O2 to _Out2. Uglify function parameters out_true and out_false. * include/bits/ranges_algobase.h (__copy_or_move): Add missing std::move to recursive call that unwraps a __normal_iterator output iterator. * testsuite/25_algorithms/copy/constrained.cc (test06): New test. * testsuite/25_algorithms/move/constrained.cc (test05): New test.
