I am not sure what is wrong here, but something is. vbo_exec_EvalCoord1fv and vbo_exec_EvalCoord1f are both static methods in that file... there is no way OpenGLInit could call them. They must be called automagically during OSMesaCreateContext or similar, but we should *see* the CreateContext call somewhere in the backtrace and I am not sure why we do not. Can you try valgrind? Perhaps somehow the generated dispatch code is jumping into lalaland and somehow magically ends up in vbo_exec_EvalCoord1fv (pretty far-fetched, but I'm out of ideas here...). -tom > at /home/kevin/kitware/VTK/Rendering/vtkOpenGLRenderWindow.cxx:241 > #2 0x00007ffff7b8c45e in vtkXOpenGLRenderWindow::CreateOffScreenWindow > (this=3D0x69d310, width=3D300, height=3D300) > at /home/kevin/kitware/VTK/Rendering/vtkXOpenGLRenderWindow.cxx:951 > #3 0x00007ffff7b8c8dd in vtkXOpenGLRenderWindow::Initialize (this=3D0x69= > d310) > at /home/kevin/kitware/VTK/Rendering/vtkXOpenGLRenderWindow.cxx:1066 > #4 0x00007ffff7b8cce3 in vtkXOpenGLRenderWindow::Start (this=3D0x69d310)= > > at /home/kevin/kitware/VTK/Rendering/vtkXOpenGLRenderWindow.cxx:1185 > #5 0x00007ffff7a54fc1 in vtkRenderWindow::DoStereoRender (this=3D0x69d31= > 0) > at /home/kevin/kitware/VTK/Rendering/vtkRenderWindow.cxx:687 > #6 0x00007ffff7a54f92 in vtkRenderWindow::DoFDRender (this=3D0x69d310) > at /home/kevin/kitware/VTK/Rendering/vtkRenderWindow.cxx:676 > #7 0x00007ffff7a54992 in vtkRenderWindow::DoAARender (this=3D0x69d310) > at /home/kevin/kitware/VTK/Rendering/vtkRenderWindow.cxx:563 > #8 0x00007ffff7a53da2 in vtkRenderWindow::Render (this=3D0x69d310) > at /home/kevin/kitware/VTK/Rendering/vtkRenderWindow.cxx:376 > #9 0x00007ffff7b8f743 in vtkXOpenGLRenderWindow::Render (this=3D0x69d310= > ) > at /home/kevin/kitware/VTK/Rendering/vtkXOpenGLRenderWindow.cxx:1845 > #10 0x0000000000432696 in TestOSConeCxx (argc=3D7, argv=3D0x7fffffffd960)= > > at /home/kevin/kitware/VTK/Rendering/Testing/Cxx/TestOSConeCxx.cxx:68= > > #11 0x000000000041b683 in main (ac=3D7, av=3D0x7fffffffd960) > at > /home/kevin/kitware/VTK_Build/Rendering/Testing/Cxx/RenderingCxxTests.cxx= > :454 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
