Dear ROOTers,
I'd like to understand and learn how to create a tree with an array
branch. I read the Tutorial section (tree3.C).
But why does the ff. line produces a segmentation problem/error messages:
--------------------------------------------------------
........
int TOTAL = 2;
float AA[TOTAL];
TTree * tree = new TTree("tree","What a nice Tree");
tree->Branch("AA",AA,"AA[TOTAL]/F");
......
--------------------------------------------------------
Pls see URLs:

http://neutrino.kek.jp/~zaldy/root_work/MyRootFaq/test.cc
while:
---------------------------------------------------------
.........
float AA[2];
TTree * tree = new TTree("tree","What a nice Tree");
tree->Branch("AA",AA,"AA[2]/F");
--------------------------------------------------------
dont.
Am using ROOTV: 3.04/02
gcc 2.91.66
Thank you.
