int f()
{
        return ({
                int x = 1;
                if (__builtin_expect((x), 0))
                        asm("");
                __builtin_expect((x), 0);
        });
}

$ g++ -x c++ -std=c++14 -c -o /dev/null idle.i
idle.i:8:10: internal compiler error: unexpected expression '<statement>' of
kind asm_expr
    8 |         });



-std=c++11 doesn't crash
-std=c++17 crashes

gcc doesn't crash


Parenthesis around (x) are important as does "1"
