This changes the version of std::ios_base::failure thrown by libstdc++.so to be the new __cxx11 ABI one, matching the default for headers that are trying to catch the exception. There's no simple way to do this as an easy transition, but hopefully by now most people are either using the new ABI or building GCC without the dual ABI. PR libstdc++/66145 * src/c++11/functexcept.cc: Use new ABI for std::ios_base::failure exceptions. * testsuite/27_io/basic_ios/copyfmt/char/1.cc: Don't override ABI for test, so new ios::failure can be caught. * testsuite/27_io/basic_ios/exceptions/char/1.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/char/ exceptions_failbit.cc: Likewise. * testsuite/27_io/basic_istream/extractors_arithmetic/wchar_t/ exceptions_failbit.cc: Likewise. * testsuite/27_io/basic_istream/extractors_other/char/ exceptions_null.cc: Likewise. * testsuite/27_io/basic_istream/extractors_other/wchar_t/ exceptions_null.cc: Likewise. * testsuite/27_io/basic_istream/sentry/char/12297.cc: Likewise. * testsuite/27_io/basic_istream/sentry/wchar_t/12297.cc: Likewise. * testsuite/27_io/basic_ostream/inserters_other/char/ exceptions_null.cc: Likewise. * testsuite/27_io/basic_ostream/inserters_other/wchar_t/ exceptions_null.cc: Likewise. * testsuite/27_io/ios_base/storage/2.cc: Likewise. Tested powerpc64le-linux, committed to trunk.
