Confirmed, reduced testcase:
struct color {
  ~color();
};
struct style {
  color col;
  style (color);
};

style::style(color c)
  : col(c)
{
}

This is the same problem that causes cc1plus to segfault building SPEC CPU2000
test eon for powerpc-linux at any level of optimization including -O0.  The
segfault happens when maybe_fold_offset_to_component_ref calls
cxx_types_compatible_p with y==0.  The failure shows up with this patch from
Jan Hubicka:
