But I confess that I have no clue as how GC works in the C code.
Will this approach work? Will menu_bar_vector be safe from GC?
You have to modify the GC code in alloc.c to explicitly find these
C data structures in the menus and mark them the vectors by calling
mark_object.
And when a struct menu_gtk_data is free:d, will menu_bar_vector
then be a candidate for GC?
No, because the code you add to GC will not find it and mark it.
Is a detached menu a Lisp object? If so, what data type is it?
Do we want a way to manipulate detached menus from Lisp?
