I may have mixed up the w and b in the example, as I was trying many
permutations.
Sorry about that. Here is the new test code I am using.

<CODE>
require 'rubyfltk.so'
w = Fltk::Window.new(0,0,200,200)
b = Fltk::Button.new(0,0,20,20,"X"){|a,b|
  #w.hide
  puts "hidden"
  Fltk.paste(w)  #(*1)
  puts "done"
}

#Fltk.paste( nil )  #(*2)

#Fltk.paste( w )    #(*3)
w.show
Fltk.paste( w )     #(*4)
Fltk.run
Fltk.paste( w )     #(*5)
</CODE>

*2 and *3 still seg-fault. 
*2 is because rb_to_fl returns NULL if VALUE is Qnil, which I don't
think Fl::paste likes.
*3 is the main problem I worry about. It seems that w.show in turn
initializes something that allows events to be sent. I tried to call
b.show and then Fltk.paste(b), but that still segfaults. So I still
suspect some FLTK wide initialization code, which may be that
Fl::check() is responcible to... uhm, check?

(I removed my code and cvs updated when I tried this.)
