<p>Hi,</p>
<p>Using GMSH 2.13.2 with FLTK 1.3.3 on Ubuntu 16.04</p>
<p>Up to now everything was working fine. <br>
</p>
<p>I did nothing at all, and at some point, 15 min after I
successfully worked with gmsh, I started getting errors</p>
<pre><code>Error : Unknown string option 'Solver.Extension0'
Error : Unknown string option 'Solver.Extension1'
Error : Unknown string option 'Solver.Extension2'
Error : Unknown string option 'Solver.Extension3'
Error : Unknown string option 'Solver.Extension4'
Error : Unknown string option 'Solver.Extension5'
Error : Unknown string option 'Solver.Extension6'
Error : Unknown string option 'Solver.Extension7'
Error : Unknown string option 'Solver.Extension8'
Error : Unknown string option 'Solver.Extension9'</code></pre>
<p>but then GMSH would still start. Later, OpenGL crashed
system-wide.</p>
<p>Would you know anything about it?</p>
<p>Greetings,</p>
<p>Aleksejs<br>
