opengl app segfaults on startup when not in gdb, backtrace points to fglrx

Asked by Jarvis Schultz

I'm trying to use the program "rviz" that is part of the robot operating system (ROS) on their groovy version. I have been using it for years, but on the newest version, I get a segfault every time I execute the program. If I run the program in "gdb" however, it runs every single time with no problems. I have already tried talking to OpenGL forums, ROS forums, and OGRE forums. I have received no help at all. Not sure if this is a valid place to ask the question, but here goes.

A coredump + gdb to postmortem reveals the following backtrace:

    Core was generated by `/opt/ros/groovy/lib/rviz/rviz'.
    Program terminated with signal 11, Segmentation fault.
    #0 0x00007fbce7bbe21c in ?? () from /usr/lib/fglrx/
    (gdb) bt

Valgrind produces an error that looks like the following:

There is aknown issue with 2xxx 3xxx and 4xxx ATi GPUs and Precise. Did you install fglrx from here:

Jarvis Schultz (jarvisschultz) said :

I was using just the version from the standard ppa. I just added the ppa you linked, and installed all relevant fglrx-legacy packages. Restarted my computer, and indeed, different versions of fglrx were loaded. "amdcccle" and fglrxinfo also reported different versions.

Unfortunately, that has not solved my issue.

Can you help with this problem?
