[PATCH] D20561: Warn when taking address of packed member

[Joerg Sonnenberger via Phabricator via cfe-commits]

joerg added a comment.

The last review left out the case of naturally aligned packed members, IIRC. I have to go over the warning list in NetBSD again, but I'm moderately sure it is not fixed.

The better example is:

  struct __attribute__((__packed__)) bar {
      uint16_t x1;
      uint16_t x2;
  };
  
  &bar->x2;

...which is not aligned.
