This is not a Mac OS specific problem.  Actually it is yet another
instance of "eval while blocking input" abort.

In xfaces.c:

  static int
  realize_basic_faces (f)
       struct frame *f;
  {
    int success_p = 0;
    int count = SPECPDL_INDEX ();

    /* Block input here so that we won't be surprised by an X expose
       event, for instance, without having the faces set up.  */
    BLOCK_INPUT;
    specbind (Qscalable_fonts_allowed, Qt);

    if (realize_default_face (f))
  ...
    unbind_to (count, Qnil);
    UNBLOCK_INPUT;
    return success_p;
  }

And the call of realize_default_face may leads to Feval through

  color_desc = call2 (Qtty_color_desc, color, frame);

in tty_lookup_color.
