--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:f54ceb2062c7fef294f85ae093914fa6c7ca35b8 commit r13-4306-gf54ceb2062c7fef294f85ae093914fa6c7ca35b8 Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Nov 24 21:09:03 2022 +0000 libstdc++: Call predicate with non-const values in std::erase_if [PR107850] As specified in the standard, the predicate for std::erase_if has to be invocable as non-const with a non-const lvalues argument. Restore support for predicates that only accept non-const arguments. It's not strictly nevessary to change it for the set and unordered_set overloads, because they only give const access to the elements anyway. I've done it for them too just to keep them all consistent. libstdc++-v3/ChangeLog: PR libstdc++/107850 * include/bits/erase_if.h (__erase_nodes_if): Use non-const reference to the container. * include/experimental/map (erase_if): Likewise. * include/experimental/set (erase_if): Likewise. * include/experimental/unordered_map (erase_if): Likewise. * include/experimental/unordered_set (erase_if): Likewise. * include/std/map (erase_if): Likewise. * include/std/set (erase_if): Likewise. * include/std/unordered_map (erase_if): Likewise. * include/std/unordered_set (erase_if): Likewise. * testsuite/23_containers/map/erasure.cc: Check with const-incorrect predicate. * testsuite/23_containers/set/erasure.cc: Likewise. * testsuite/23_containers/unordered_map/erasure.cc: Likewise. * testsuite/23_containers/unordered_set/erasure.cc: Likewise. * testsuite/experimental/map/erasure.cc: Likewise. * testsuite/experimental/set/erasure.cc: Likewise. * testsuite/experimental/unordered_map/erasure.cc: Likewise. * testsuite/experimental/unordered_set/erasure.cc: Likewise.
