I believe you’ve found a real bug in cint. And I believe Alex will take care of it … just needs time.
I also get problems (reported by you) when I do:
root [0] #include
root [1] vector< vector > i
and/or when I do:
root [0] #include
root [1] vector<vector> d;
root [2] vector dd;
root [3] dd.push_back(2);
root [4] d.push_back(dd);
A similar issue involving “vector< pair<> >” has been reported here: [url]Vector< pair<> >
