Crash everytime

Hello,

I have this grasshopper definition with Karamba. Almost every time I try to modify a slider or something, rhino crashes. 

I'm joining the crash report file and the GH file of the definition. 

Although i wanted to ask, is there a way (not the one i used in the definition) to make a full cross section, not a box or a circular hollow. My results are really awkward and I think it might be related. 

Thank you for your help
