crash log

I get this assertion when I enable optimization (-O1, -O2, -O3, -Ofast, -Os or
-Og but not -O0 or nothing) for almost every program. This is one of them:

#include <iostream>

int main() {
  std::cout << "Hello World\n";

The CodeGen tests fail miserably as a result too.
I attached the log crash for that hello word program and with -03.
