I wrote a class deriving from TSelector, with the goal of having dynamic behavior based on what branches were present, what type they had, etc.
What I wrote compiles fine, and runs fine on a single file, but crashes during fChain->GetTree()->GetEntry(entry) when another file is reached. In fact, in some cases, root simply exits without any crash or message at all…
Any suggestions would be highly appreciated.
Thanks,
Andrew Meade
What I’m doing (simplified a bit):
header:
map<string, vector *> myVarMap;
Init():
…
fChain->SetBranchStatus("*",0);
if (some condition) {
fChain->SetBranchStatus(“branchName”,1);
vector * myVec = new vector;
myVarMap[“myVar”] = myVec;
fChain->SetBranchAddress(“branchName”, &myVec);
}
The crash I get:
*** Break *** segmentation violation
