Welcome to the ROOT Forum!
That might be one of the SetBranchAddress which is wrong, and BTW, you should initialize your variables to 0, like int eventID0 = 0 and are you sure all those branches are integers?

Valgrind might points to the real problem.

Also can you copy/paste the result of Singles->Print(); ?
