// Simple binary that will just crash with the message given as the first parameter.

//

// This is helpful in cases the caller does not want to crash itself, e.g., fork+crash

// instead, as LOG(FATAL) might not be safe (for example in a multi-threaded environment).

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

    if (argc != 2) {

        LOG(FATAL) << "Need one argument for abort message";

        __builtin_unreachable();

    }

    LOG(FATAL) << argv[1];

    __builtin_unreachable();

}
