Dear all,

I would like to run a reconstruction with the secondary track finder. I simulated 1000 events for pbarp → Xi(1820)- Xibar+ with a beam momentum of 4.6 GeV/c.
I run the reconstruction with the attached reco_secondary_trackfinder.C macro. But the macro breaks at some point
*** PndGenfitAdapters::GenfitTrack2PndTrack	could not convert GenfitTrack to PndTrack
*** PndGenfitAdapters::GenfitTrack2PndTrack	could not convert GenfitTrack to PndTrack
*** PndGenfitAdapters::GenfitTrack2PndTrack	could not convert GenfitTrack to PndTrack

 *** Break *** segmentation violation

There was a crash.

(for full error message see log-file).
On my machine I am using the following software versions:

FairRoot: nov15p5
FairSoft: v15-11c
PandaRoot: trunk rev. 29165

Does anyone of you observe the same problem or has an idea how to fix it?

Best regards,
