[Gate-users] Regular Parameterization Error with Geant4 v10

[Triltsch, Nicolas]

Hello,

I tried to speed up my simulation by choosing Regular Parameterization 
(with flag skipEqualMaterials to 1) instead of Nested Parameterization, 
because my Volume got a lot of voxels with the same material. It did 
indeed speed up the simulation by a factor of 15, but some projections 
of my CT simulation failed (error: segmentation fault; crash).

Now I saw that during the initialization phase of gate it states the 
following:

/### WARNING ### setSkipEqualMaterials at false !! The Geant4 method is 
not safe since the release 9.5 - Need to be fixed/

I am pretty sure that this warning is somehow connected to the warning. 
Does anyone know if there had been a bug fix for Geant4 v10.2.2?

In the appendix there is a screenshot of the error.

Cheers,
Nico
