Agreed. It is not an octave issue, it seems to be a mesa/dri problem... Thanks for your effort and sorry for the inconveniences.
Best, F.

You could try building the development branch from Mercurial sources. Otherwise, I would say that this is likely to be a computer-specific issue: either your OS (Slackware) or your specific combination of OpenGL HW, drivers, and configuration files.

I tried the 4.2.1 release but I still get a segmentation fault.

The simplest thing might be to try the 4.2.1 bug fix release which was put out today. See ftp://ftp.gnu.org/gnu/octave. Over 50 bugs have been resolved including some tricky ones with segfaults and OpenGL.

Dear all,

I have encountered the following problem. Octave GUI exits with signal 11 after double click inside a figure window of a
loglog plot (or semilogy plot) when using qt graphics toolkit. Using gnuplot or fltk instead works fine.

The crash occurs for example using commands
and a double click inside the figure window. However
do not crash.

The output of a gdb session after a "loglog plot crash" can be found in the attached file.

I am runnung Slackware64 14.2 (kernel 4.4.38, multilib / 32bit compatibility libs installed) on a thinkpad T460p with hybrid-graphics:
VGA compatible controller: Intel Corporation Device 191b (rev 06)
3D controller: NVIDIA Corporation Device 134d (rev a2)
using only the intel gpu.
uname -a gives
SMP Sun Dec 11 16:18:36 CST 2016 x86_64 Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz GenuineIntel GNU/Linux

octave-4.2.0.tar.lz was patched with atlas-lib-rename.diff and
compiled using Intel MKL

Some (presumably) relevant installed packages are

Any help would be appreciated.
