Since this works with the latest stable release of Octave I'm going to close this report. I realize it is still a problem for ancient versions of Octave, but we have only a small volunteer crew and have to prioritize more recent versions.

With the address sanitizer enabled I get a "heap-buffer-overflow" wether I use Qt(5) or fltk. Evven though I have debug symbols enabled the bt does not mention the actual functions in which this happens

The software trick doesn't work.

Agreed. Have the original reporter try the LIBGL_ALWAYS_SOFTWARE trick. If it works then the problem is shifted back to a HW driver and the reporter's equipment.

The sample code also works for me in Octave 3.8.2.

A simpler variant of the original sample code is

I think this crash is probably dependent on the video hardware and OpenGL support as with many other reported plotting bugs.

Yes, that's what I thought. The problem is that policy is to not undergo major version updates in the Enterprise Linux packages...

And yes, the test case works with octave-4.2.1-3.fc26.x86_64 on my Fedora 26 workstation.

Octave 3.8.2 is deprecated and is two generations back and won't be fixed. Can you check whether this is a problem with the latest stable release (4.2.1)? The sample code works for me.

For reference, the test code is:

As reported on the Fedora bugtracker
https://bugzilla.redhat.com/show_bug.cgi?id=1505895

octave 3.8.2 crashes with the fltk frontend when trying to mesh plot the sombrero example.

I can reproduce the crash on my computer, but unfortunately I can't give a backtrace...
