Re: NT Emacs crashes when selecting a menubar item

[Richard Stallman]

Is this comment in w32menu.c inaccurate?

      /* Now GC cannot happen during the lifetime of the widget_value,
         so it's safe to store data from a Lisp_String, as long as
         local copies are made when the actual menu is created.
         Windows takes care of this for normal string items, but
         not for owner-drawn items or additional item-info.  */

If it is inaccurate, why is that?  How is it that GC happens in
between creation of the widget value and its use in add_menu_item?
Note that GC ought to be inhibited within set_frame_menubar
from this line

      inhibit_garbage_collection ();

to this line

      unbind_to (specpdl_count, Qnil);

Does the GC happen inside that range, or after?
Either way, it's a bug; the question is what bug.
