Hello
Seems the problem is not only with 'long long' but with any casting
performed outside of code blocks
int a = 2.0 ? 0 : 1;
int b = (_Bool)2.0;
int c = !2.0;
int d = 2.0;
int e = (char)500;
int main()
{
printf("%d %d %d %d %d\n", a, b, c, d, e);
}
GCC output: 0 1 0 2 -12
TCC output: 1 0 1 0 500
