Hi Sebastien,
As I said, I cannot reproduce your problem. see below:
root [0] TClonesArray* array = new TClonesArray("class",10) ;
Error in <TClonesArray::TClonesArray>: class is not a valid class name
root [1] if(array->IsZombie()) cout << "is zombie" << endl ;
is zombie
root [2]

Error in <TClonesArray::TClonesArray>: class is not a valid class name
root [1] if(array->IsZombie()) cout << "is zombie" << endl ;
is zombie
root [2]iously gives an error message since class is not known but
