I have encountered a segfault in Octave when plotting any graph, then clicking on it in the window that appears.  I'm running GNU Octave 4.0.0-7 on Arch Linux x86_64, with Mesa 11.1.2-1.

I do not think this is a bug in Octave (see https://savannah.gnu.org/bugs/?func=detailitem&item_id=45863 where they claim this is not an Octave bug).  I have also attached a backtrace and core dump; hopefully these will prove useful.  (Beware that the core dump expands to 450MB!)  In addition, the crash is very reproducible, so let me know if I can provide further data.

More evidence suggesting that this is not an Octave bug: running Octave under my discrete Nvidia graphics card (using Bumblebee) allows the graph to function correctly.
Comment 2 George Hilliard 2016-04-05 22:31:26 UTC 
I can no longer reproduce this with Mesa 11.1.2 and Octave 4.0.1.
