--- Comment #9 from frs.dumont at gmail dot com --- Here is the reason of the 20_util/specialized_algorithms/pstl/uninitialized_copy_move.cc FAIL. Maybe it fixes some other tests too, I need to run all of them. libstdc++: Do not forward arguments several times [PR90276] Forwarding several times the same arguments results in UB. It is detected by the _GLIBCXX_DEBUG mode as an attempt to use a singular iterator which has been moved. libstdc++-v3/ChangeLog PR libstdc++/90276 * testsuite/util/pstl/test_utils.h: Remove std::forward<> calls when done several times on the same arguments. Ok to commit ?
