Uhmmm...maybe I was too optimistic yesterday on the trunk rev-21003.
I tried all /tutorial/rho macros over a reduced sample of 100 events on 2 different analysis, and everything looked working smooth. Today I tried to run more events. Here I attach the file.dec which I am currently using, and the sim-macro, where the only modified parameter compared to the tutorial sim-macro in /tutorial/rho/ is the momentum (I am running a simulation for the psi(4040)).
I also attach here the plot of the psi(4040) which I obtain running the first 200 events, and it looks ok (true pid).
I made 5 attempts before posting this message, and I got a segmentation fault always at the same point: event #216
I am running a sample of 5000 events right now.
tut_sim.C OK
tut_digi.C OK
tut_rec.C OK
tut_pid.C it crashes at the event #216
Here below is the error message. Any idea what is going wrong? Did anybody meet the same problem before? is there the possibility to flag/exclude an event in pandaroot simulations?
I see here a "kSigFloatingException" break.
Just an idea: I am using PHOTOS. Can we use it in PANDA or is it still too soon? In this simulation my J/psi decays to mu+ mu- using the model VLL, and to e+e- using the model VLL + PHOTOS for electrons only.
Thanks for any hint, Elisabetta
