Using the recent reply of Tue Mar 22, 2011 17:29 found in [url]Composite Shapes cause bus error in gdml export this long-standing problem can finally been “solved”.
In the “Det.C” source code file, one needs to replace:
TGeoVolume *PIPF1 = new TGeoVolume(“PIPF1”,PIPR1);
TGeoVolume *PIPF2 = new TGeoVolume(“PIPF2”,PIPR2);
with something like:
TGeoVolume *PIPF1 = new TGeoVolume(“PIPF1”,PIPR1, med1);
TGeoVolume *PIPF2 = new TGeoVolume(“PIPF2”,PIPR2, med1);
