<br>This bug was introduced after upgrading to Octave 3.8.1-1+b1,<br>and the bug was not there in 3.8.0 (I am not sure about this<br>version number. I can only remember that it was already 3.8, <br>introducing the experimental gui).<br>
<br>Just fresh install octave:<br><br>$ sudo apt-get update<br>$ sudo apt-get upgrade<br>$ sudo apt-get install octave<br><br>Then open octave [using --norc/--no-gui/--jit-compiler does<br>not affect the segfault]:<br><br>

A figure window opens, and then closed again after the segfault.<br><br>If we try opening figure by itself calling `figure', there was<br>no segfault, until one of the following operations was performed:<br><br>1. Pushing `A' button at the down-left corner, or Edit->Autoscale<br>
2. Pushing `G' button at the down-left cornet, or Edit->Grid<br><br>Any other interaction with this figure does not crash octave.<br><br><br>P.S. I am not sure if this is the same problem, but I think it is<br>better to include it here. After installing octave-psychtoolbox-3,<br>
calling DrawSomeTextDemo or DotRotDemo provided by psychtoolbox, <br>also crashes with segfault, though this does not use figure. That<br>package extensively uses OpenGL.<br><br><br><br><br>-- System Information:<br>Debian Release: jessie/sid<br>
