[Gmsh] gmsh 2.0.8 aborts or segfaults

Hello again,

Just a quick follow-up on the problem reported previously:

The second geo file attached to the previous email, which shows the 
problems, has a bunch of distorted volumes, which show up when rendering 
the geo file in gmsh. Usually my scripts remove these volumes and they 
do not appear to cause the segfault problems.

Attached another example, which causes gmsh to segfault. This time 
without the distorted volumes.

When opening this geo file with gmsh in the graphical user interface, 
gmsh throws these errors:

gmsh media_p03.geo

Info    : Reading 'media_p03.geo'
Error   : Weird point 554 in Coherence
Error   : Weird point 554 in Coherence
Error   : Weird point 510 in Coherence
Error   : Weird point 510 in Coherence
Error   : Weird point 510 in Coherence
[...]

However, gmsh does display a reasonable geometry.

Meshing leads to the segfault:

gmsh -3 media_p03.geo
(Mesh.Algorithm3D=4;)

Info    : 16 points, 23 elements
Info    : Meshing volume 23 (Netgen)
Fatal   : Segmentation violation (invalid memory reference)

gmsh -3 media_p03.geo
(Mesh.Algorithm3D=1;)

Info    : Meshing volume 473 (Delaunay)
Info    : Meshing volume 474 (Delaunay)
Fatal   : Segmentation violation (invalid memory reference)


Thanks in advance for any help.


Werner
