Thanks for the extra information. I know very little about Radeon graphics configurations, but this looks to me suspiciously like a poorly configured Radeon setup that does not fully support OpenGL graphics. Having a working OpenGL configuration is a prerequisite for using the FLTK plotting backend. There is an open upstream bug report about gracefully reporting an error under such conditions, so this is a known problem.
It appears to me that we can pursue this crash from one of two angles: 1. Continue treating this as a bug that Octave should not crash with a segmentation fault when sufficient OpenGL support is lacking. The outcome of a potential fix for this bug would simply be an error message saying that you are unable to use FLTK. 2. Convert this to a support question and we address your system configuration so you can get OpenGL and FLTK plots working with your Radeon video card. Which of these look most appropriate to you? Of course if you *do* know about Radeon graphics configuration and you can prove that your system *is* correctly configured for full OpenGL support, and Octave still crashes using FLTK, then something else is going on here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1294116 Title: Segmentation fault while calling subplot function To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1294116/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
