Hi all,
I have been able (finally) to reproduce the error on another computer, and I see the crash at event 175 like you Ralf (I used your simulated file).
I tried to understand the bug source: in the hit producer two TClonesArray (fHitArray and fHitInfoArray) are created and registered to output; I saw that commenting out one of the two lines where the "new" is called, I mean:
the line: hit = new ((*fHitArray)[counter]) PndSttHit(detID, pos, dpos, iPoint, 0, closestDistance, closestDistanceError, wireDirection);
or the line: new ((*fHitInfoArray)[counter]) PndSttHitInfo(0, 0, trackID, iPoint, 0, kFALSE);
the bug disappears, but actually I don' t know what does this mean, does anyone have any idea?
It should not be due to a memory leak (I have been able to digitize an event with 170 hits, so 83 should not create problems), but I don' t know...
I checked the code, but I can' t find the actual error 
So this is my idea: I would suggest to wait and see if the bug will appear again with a future ROOT version (when we will update it: maybe it is connected with this version and it will disappear (I really hope so).
For the moment let' s keep the workaround of the seed changing. What do you think?
Ciao,
Lia.
