Thanks Robert, using MESA 7.0.2 (compiled in pure software, no dri) -> "osgviewer mymodel.fmt --SingleThreaded" crashed at the second 'S' as usual using MESA 7.0.0 (compiled in pure software, no dri) -> "osgviewer mymodel.fmt --SingleThreaded" crashed at the second 'S' as usual using MESA 6.4.2 (compiled in pure software, no dri) -> "osgviewer mymodel.fmt --SingleThreaded" no problems
It seems that the latest MESA release introduced some bugs, at least with my configuration/system: Ubuntu 7.04 / GCC 4.1 / Xorg 7.2.0 / Core 2 Duo T7300, so I will stick to MESA 6.4.2. It would be interesting to know if anyone else can reproduce the crash in another system using MESA 7.0.x, if it's really a bug we could report it to the MESA guys.
