Bug#607875: gmsh: Segmentation fault when creating 3d mesh

[Torquil Macdonald Sørensen]

Package: gmsh
Version: 2.5.0.dfsg-2
Severity: important

Gmsh segfaults when I ask it to generate a 3d mesh. I have attached a
*.geo.gz file which has a 3d arc with a defined volume.

To reproduce the segfault, just open it in Gmsh, select "Mesh" in the drop-down
menu, then click on "3D".

Gmsh segfaults with the following message on the terminal:
