Hi Andrea, The interaction with the NVidia control panel really suggest an OpenGL driver bug.
The stack traces suggest a database reading bug... Is there a chance it could be gcc bug though... try and compile with -O2 rather than -O3 to see if makes a difference. Another long shot might be a physical memory error, it doesn't happen very often, but it has happened in the past that flaky machines have caused weired memory related crashes. FYI, I develop under Linux, on a dual core machine, and test on dual 7800GT + paged database regularly and don't see crashes on any of the terrex or osgdem generated databases I have. Robert.

Hello all, we are experiencing random crashes in the OSG applications we are developing under Linux (realtime image generation with large area PagedLOD databases). After several debugging sessions, I think I have been able to isolate the problem further. These factors do not seem to influence the problem: OSG application - crashes happen also with the standard osgviewer OS version - tested under Fedora Core 3 / 4 OSG version - both OSG 1.2 and OSG 2.0 have the same problem PagedLOD database - tried with several databases, created with osgdem or with custom built applications, or even in TXP format Nvidia driver version - tried Linux versions 8174 and 9755 The problem instead seems related to the Nvidia control panel: I am able to always trigger the crashes by launching the Nvidia control panel (nvidia-settings) and forcing Antialiasing and Anisotropic filtering on. After that, If I close the control panel and launch any osg application with paging, after a very short time the app segfaults. From that moment on, no matter what are the settings in the Nvidia control panel, every app crashes regularly, after a varying (short) amount of time. Following are some examples of debugger traces (osgviewer pagedDB.ive) after the crash. Note that the memory usage for the application is very low (7-8% at the moment of crash). Do you have any clue to where could be the problem?
