My program uses osgViewer::StatsHandler, but when I press 'S' the second time to show the extended statistics it crashes with the following back-trace. The strange thing is that if I press 'S' only once the program shows the FPS without problem, but if I press 'S' again it crashes. Did anyone experienced the same problem? Note that the program crashes only on my Ubuntu 7.04+Mesa 7.0.2 box and not under WinXP.
