Hi,
I’m trying to write a static member of a class (a TClass*) to file by adding it to the UserInfo of a TTree. This was recommended a while ago (2009) as a performant solution (Rootcint and static data members). Whenever I try to do this the program crashes when it reaches a call to TParallelMergingFile::Write.
At which point is it recommended to set the user info of the tree? In the clients before the trees are merged, or after the merge has already happened?
Cheers,
Vinzenz
