The following fails with 32bit pointers and 64bit long long if the compiler is
built with type-checking enabled.

void __lock_get_list(void *dp)
{
  if (((unsigned int)dp + 1) & ~1ULL)
    ;
}

The original trees look ok:

  if (((long long unsigned int) (dp + 1) & 0x0fffffffffffffffe) != 0)
    {
      (void) 0;
    }
