It crashes at the following xassert in set_lface_from_font_name:

      if (have_xlfd_p)
	pt = xlfd_point_size (f, &font);
      else
	pt = pixel_point_size (f, font_info->height * 10);
      xassert (pt > 0);

In Carbon Emacs, the value of `pt' possibly becomes 0 because the
`full_name' field in `struct font_info' may not be fully instantiated
and it may contain 0 in the XLFD pixel size field.  Please try the
attached patch.
