Hi,
I downloaded the may11 release and run the macros there, but I still get all the crashes.
I thought that it might be something wrong in the macros (maybe I changed something and did not remember), so I took the macro/run/tdrct/eta_c macros for the stt and just changed the generator part to simulate single muon tracks instead of etac events, but I still get the crashes.
I run six tests and only one arrived to the end without problems.

Ralf, can you please have a look into this, as Tobias suggested?

An alternative solution could be to put inside genfit some protection against the division by 0 in the invertMatrix function of GFTools.cxx, but the strip errors equal to 0 would be still there. What do genfit people think about this?
Cheers,
Lia.
