LWG 4172 was approved in Hagenberg, February 2025, fixing std::unique_lock and std::shared_lock to work correctly for self-move-assignment. Our std::shared_lock was already doing the right thing (contradicting the standard) so just add a comment there. Our std::unique_lock needs to be fixed to do the right thing. libstdc++-v3/ChangeLog: * include/bits/unique_lock.h (unique_lock::operator=): Fix for self-move-assignment. * include/std/shared_mutex (shared_lock::operator=): Add comment. * testsuite/30_threads/shared_lock/cons/lwg4172.cc: New test. * testsuite/30_threads/unique_lock/cons/lwg4172.cc: New test.
