There's now an "excess error": x/libstdc++-v3/testsuite/23_containers/bitset/45713.cc:24:55: error: size of array 'test' is not an integral constant-expression int test[sizeof(std::bitset<0xffffffff>) != 1 ? 1 : -1]; Or is the error message in error and just "missing" before? Please have a look. brgds, H-P
