--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> 2012-10-09 15:29:12 UTC ---
Err,

static tree
prune_expression_for_jf_1 (tree *tp, int *walk_subtrees, void *)
{
  if (EXPR_P (*tp))
    SET_EXPR_LOCATION (*tp, UNKNOWN_LOCATION);
  else
    *walk_subtrees = 0;
  return NULL_TREE;
}

of course.
