Re: checking result of SetBranchAddress

OK, that makes sense. (So SetBranchAddress does not set the address of the branch as one might deduce from its name :)

The problem however remains, as on a failure of SetBranchAddress the pointer is modified, too:

--> StacoMuon_nucone20 before (nil)
--> now is 0x8e2797c

--> StacoMuon_bestMatch before (nil)
Error in <TTree::SetBranchAddress>: The pointer type give (vector<bool>) does not correspond to the class needed (vector<int>) by the branch: StacoMuon_bestMatch
--> now is 0x8e27980
