Hello All,
I have a TTree with many branches contains std:vector. I would
like to access a specific subset of these Branches. A way I thought of
doing this would fill a vector with a pointers to the branches I want
and fill another vector with pointers to the vectors in the Branches. This
part I can achieve just fine but when I try to load an entry from the tree
I get a crash with the below output.
I have attached files which reproduce the crash.
gmake
./test
Any help is appreciated.
