--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
The diagnostic is long fixed but the folding failure / const promotion issue
remains:

f ()
{
  static char key[4] = "abc";
  char * p;
  int _1;
  char _2;

  <bb 2> [local count: 153142428]:

  <bb 3> [local count: 1020054733]:
  # p_12 = PHI <";"(2), p_8(6)>
  _1 = __builtin_strncmp (p_12, &key, 3);
