--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
PR85803 - I'd say this bug is a duplicate (to some extent).  Simplified
testcase
that, with the help of alarm() and signal handlers could be turned into a
runtime FAIL.

typedef __SIZE_TYPE__ size_t;
void move_up(void *p)
{
  for ( size_t* i=(size_t *)(p); ; )
    {
      *i=0x0700070007000700;
      if (i == (size_t *)(p)+2 )
        break;
      ++i;
    }
  while (1){}
}
