[cfe-dev] std::use_facet<std::ctype<char>> crashes on linux

[toki loki]

Hi,

Program

#include <locale>

int main(int argc, char* argv[]) {

    std::locale loc;

    std::use_facet<std::ctype<char>>(loc);

    return EXIT_SUCCESS;

}


Crashes with latest libc++ and libc++abi on Linux with backtrace

I have found that 'std::ctype<char>::id.__get()' is 28 for me. I have
constexpr enabled.

Thanks.
