[Gmsh] crash when meshing 'cleaned' STEP file

[Zenker, Dr. Matthias]

Hi,

I am working on a method to 'clean' STEP files in order to get a
conformal mesh between adjacent bodies. If I get it to work, I will be
happy to share it, but I am still struggling at the moment...
My problem is that gmsh will not mesh my 'cleaned' geometry. What I try
to do is to determine the surfaces and lines which are identical, delete
the unnecessary ones and redefine the volumes using the remaining
surfaces. I use an external tool (scilab script), so I did not modify
gmsh. Please find in the attachment my test geometry in STEP format and
the geo file I want to use for the 3D mesh. gmsh does the 2D and 2D
meshing without problems, but crashes during the 3D mesh (either I get a
net crash, or gmsh does not respond any more after some time, and I have
to kill it). Did I do something wrong when generating the geo file? I
would be very happy if someone could have a look on my case.
I am using gmsh 2.5.1svn under Windoze XP.

Thank you for any hint,

Matthias
