Reduced a little more:

/* ./cc1 -O1 pr18519.c */

int baz (int *);
                                                                               
                    
void
foo (int *uc)
{
  int *invalidp;
  int invalid;
                                                                               
                    
  while (1)
    {
      invalidp = &invalid;
                                                                               
                    
      if (baz (uc))
        invalid = 1;
                                                                               
                    
      invalid = 0;
    }
}
