Hi Florian,
your code snippet indeed fixes the double free crash at the end of the macro. However the lmd uses a special backtracking task, more precisely FairGeane & FairGeaneApplication. I still get the same double free crash report in the geant3 initialization phase (see log below). It crashes in the Geant3 vmc InitMC() function. From the stack trace it looks like that the problem is the same as before, something inside the TGeoManager getting deleted again that was deleted before.

I managed to overcome this problem, by adding the first two lines of your code snipped in the FairGeaneApplication. However I need to verify that the physics results are meaningful once i have the simulation macro running...
void FairGeaneApplication::ConstructGeometry()
{
TVirtualMC::GetMC()->SetRootGeometry(); // notify VMC about Root geometry
gGeoManager->GetListOfVolumes()->Delete();
gGeoManager->GetListOfShapes()->Delete();
}
Thx for the help.
Stefan
