SttHitCorrector giving segmentation violation [message #23030] Fri, 05 October 2018 11:22

Hi everyone!

When running the SttCellTrackFinder and using the SttHitCorrector, a segmentation violation occurs when reading in the reconstruction root file (into e.g. a macro) which was created when running for a larger (<20) number of events. The problem seems to be connected to FairTimeStamp objects which read too few bytes, there are objects of this type which is basically non existent and reading 2 bytes. I have run tests with different versions of PandaRoot, FairRoot and FairSoft to be sure it is not an issue with the versions. The FairTimeStamp objects and objects derived from this class, e.g. FairHits read too few bytes also when running the SttCellTrackFinder without the SttHitCorrector extension. The data in the Root file is accessible in both cases and look reasonable but when including the extension, at some point an event can not be read in by e.g. a macro. Below I include the error messages from after trying to read the events from the ROOT file after having used the SttHitCorrector. If someone have an idea what the problem might arise from I would be happy to hear about it!

Best,
Jenny
