Dear framework specialists,

I have problems running my macros since I updated the base folder in the trunk. Downgrading to revision 11176 solves the problems.

Specifically, I get a segfault when adding my MC output file as a friend in the digi or reco macro:

#9  <signal handler called>
#10 0xb393a8c3 in FairRootManager::AddFriendsToChain (this=0xa5eb9f8) at /home/date/pandaroot/trunk_new/base/FairRootManager.cxx:1019
#11 0xb394bc0f in FairRunAna::Init (this=0xa0b8be8) at /home/date/pandaroot/trunk_new/base/FairRunAna.cxx:107


Looking into it I found that in the loop over the items in "friendList" in AddFriendsToChain():

  • It finds my MC-file as first entry in the list
  • The only inputlevel is "InputChain"
  • The TChain* of fFriendTypeList["InputChain"] is NULL
  • Consequently, the following addFile() gives a segfault


What is going on? Surely something is wrong in my macros, since nobody else seems to have problems. However, as I mentioned, downgrading the base folder solves the problem. Maybe somebody of the experts can give me a hint here?

Cheers

Felix
