--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
  type = signed_type_for (TREE_TYPE (e1));
  tree_to_aff_combination (e1, type, &aff_e1);
  tree_to_aff_combination (e2, type, &aff_e2);

signed_type_for (offset_type 0x7ffff6d9cc78)

returns NULL_TREE.  OFFSET_TYPE in the IL ... ugh.

void fn1(A<int>&, int Layer::*, int) (struct A & p1, <<< Unknown tree:
offset_type >>> p2, int p3)
{


I have a patch.
