--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
So I managed to commit to trunk:

+  poly_uint64 this_max_nunits = 1;
   slp_tree res = vect_build_slp_tree_2 (vinfo, stmts, group_size, max_nunits,
                                        matches, npermutes, tree_size,
bst_map);
-  /* Keep a reference for the bst_map use.  */
   if (res)

while to the branch (correct):

+  poly_uint64 this_max_nunits = 1;
+  slp_tree res = vect_build_slp_tree_2 (vinfo, stmts, group_size,
+                                       &this_max_nunits,
                                        matches, npermutes, tree_size,
                                        max_tree_size, bst_map);
-  /* Keep a reference for the bst_map use.  */

oops.
