I tried to run run_reco_sttcombi from feb. 2012 tutorial (the trunk 18125 is used). And I got a following crash caused by PndSttMvdTracking.cxx using

*****************************************************************
This crash happened for some events with big values of track stt hits (nSttParHitsinTrack was 56 and nSttSkewHitsinTrack was 43) in PndSttMvdTracking.cxx. Therefore in PndSttMvdTracking.h I increased nmaxSttHitsInTrack value from 60 to 150. It fixed the problem and this crash was disappeared.
