--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
If I change zix_btree_iter_is_end to:

ZIX_API bool
zix_btree_iter_is_end(const struct ZixBTreeIterImpl* const i)
{
  if (!i)
    return 1;
  if (i->stack[0].node == NULL)
    return 1;
  return 0;
}

Then both the C and C++ front-end generated IR causes the segfault.
