Dear John,

Yes, I am coding my myself. This snippet is actually from my extension of GDML. The nodes and facets I got from triangulation of the solid, using a CAD tool. I exported it into STL format, so I get this image.

I am sorry that I made a small mistakes on the function name. What I called is HepPolyhedron::createPolyhedron. The segmentation fault happened in the HepPolyhedron::SetReferences().

I've check my reader code for the GDML extension, there is no obvious error.

Best regards,

Yuefeng
