As reported at the L3 filtering meeting this afternoon, I experienced serious problems when trying to run tsim_l3 (the default from the release or my own build) from t02.10.00 and t02.09.00. Once issues like tools.rcp not containing Width_EM1/2/3 (in t02.09.00), I was all the time crashing in the end in the destructor of the physics results in L3ToolResults.hpp. Varying trigger lists and data sets (raw data or MC) didn't help, but just convinced me it was not due to the tau tool (where I discovered the crash at first) since the crash happened then in other tool results destructors. Checking this code I noticed it had be rewritten compared to p11, so I took the code from p11 instead and managed to make the executable run without crashing with the trigger list in /work/uppsala-clued0/yann/level3sim/tauonly/level3.sim, on the test sample /d0usr/products/TestData/NULL/v00-01-20/d0sim113.isajet.ttb_10evts_188143620_2000 (which is $raw_ttbar_10). That was enough for my purpose, put even so there are still strange things going on: trying to run exactly the same thing sometimes it crashes sometimes it doesn't... I am out of town starting tomorrow morning until April 6 so I cannot give you more info if you need, but please have a look at it. Maybe it's my fault and you won't reproduce the bug, I would be happy with this!
