Date: Thu, Dec 23, 2010 at 2:10 PM<br>Subject: Bug#607875: gmsh: Segmentation fault when creating 3d mesh<br>To: Debian Bug Tracking System <<a href="mailto:submit@bugs.debian.org">submit@bugs.debian.org</a>><br><br>
<br>Package: gmsh<br>
Version: 2.5.0.dfsg-2<br>
Severity: important<br>
<br>
Gmsh segfaults when I ask it to generate a 3d mesh. I have attached a<br>
*.geo.gz file which has a 3d arc with a defined volume.<br>
<br>
To reproduce the segfault, just open it in Gmsh, select "Mesh" in the drop-down<br>
menu, then click on "3D".<br>
<br>
Gmsh segfaults with the following message on the terminal:<br>
