I am using OpenGL 4.1 on MacOS. I tried calling Fl_Gl_Window::draw() at the end of my GL viewport widget and was greeted with a crash in gl_draw / gl_font.

I'm not sure if I understand this correctly. What means "at the end of my GL viewport widget"? Does this mean at the end of the constructor?

    I read that to mean he's calling Fl_Gl_Window::draw() and the bottom of his widget's draw()
    because he (probably) has FLTK widgets that are children of his Fl_Gl_Window derived widget.

    According to the docs, your draw() is supposed to do all the GL stuff, then the last thing
    you do before return()ing is to call Fl_Gl_Window::draw() so that the child widgets can
    be drawn over your opengl drawing.
