The pmr aliases for basic_string and match_results are incompatible with the gcc4-compatible ABI because the Copy-On-Write basic_string class doesn't support C++11 allocators. PR libstdc++/87061 * include/experimental/regex [!_GLIBCXX_USE_CXX11_ABI] (experimental::pmr::match_results, experimental::pmr::cmatch) (experimental::pmr::smatch, experimental::pmr::wcmatch) (experimental::pmr::wsmatch): Do not declare for gcc4-compatible ABI, because COW strings don't support C++11 allocator model. * include/experimental/string [!_GLIBCXX_USE_CXX11_ABI] (experimental::pmr::basic_string, experimental::pmr::string) (experimental::pmr::u16string, experimental::pmr::u32string) (experimental::pmr::wstring): Likewise. * include/std/regex [!_GLIBCXX_USE_CXX11_ABI] (pmr::match_results) (pmr::cmatch, pmr::smatch, pmr::wcmatch, pmr::wsmatch): Likewise. * include/std/string [!_GLIBCXX_USE_CXX11_ABI] (pmr::basic_string) (pmr::string, pmr::u16string, pmr::u32string, pmr::wstring): Likewise. * testsuite/21_strings/basic_string/types/pmr_typedefs.cc: Require cxx11-abi. * testsuite/28_regex/match_results/pmr_typedefs.cc: Likewise.
