Package: liblablgl-ocaml
Version: 1.02-2
Severity: normal


Simple lablgl program:

    let init () =
        GlClear.color (0.0, 0.0, 0.0)
    
    let display () =
        GlClear.clear [ `color ; `depth ] ;
        Glut.swapBuffers ()
    
    let right_menu ~value =
        Printf.printf "right_menu %d\n" value ;
        flush stdout
    
    let _ =
        ignore (Glut.init Sys.argv) ;
        Glut.initDisplayMode ~depth:true ~double_buffer:true () ;
        Glut.initWindowSize ~w:500 ~h:500 ;
        ignore (Glut.createWindow ~title:"OpenGL : Cone Culling Example") ;
    
        ignore (Glut.createMenu right_menu) ;
        Glut.addMenuEntry "One" 1 ;
        Glut.addMenuEntry "Two" 2 ;
        Glut.addMenuEntry "Three" 3 ;
        Glut.attachMenu Glut.RIGHT_BUTTON ;
    
        Glut.displayFunc display ;
    
        init () ;
        Glut.mainLoop ()

Compile with:

    ocamlopt -I +lablGL lablgl.cmxa lablglut.cmxa right_menu.ml -o test

and run program. Now right click and select one of the three options and
the program segfaults. Gdb backtrace below:

Indeed, I am able to reproduce this bug in Etch. But not in Lenny. I
guess it has been fixed meanwhile. I am therefore closing this bug.
