We also have a few miscompilations. Here's a reproducer for which we produce the wrong result:

  short short1, short2, short4;                                                                                    
                                                                                                      
  int main() {                                                                                          
    short2 = 5;                                                                                         
    short3 = -6;                                                                                       
    assert((short1 = ~short2) == short3);                                                              
  }
