Hi,

why does the follwing work on Linux (Suse 7.3, root 3.02/06) but not on
Alpha (Tru64 Unix 5.1, root 3.02/07):

void *ptr = NULL;
TFile file("name", "RECREATE", "", 9);
TTree *T1=new TTree("P", "");
TTree *T2=new TTree("E", "");
TBranch *B1=T1->Branch("MPhoton.",   "MPhoton",   &ptr);
TBranch *B2=T2->Branch("MElectron.", "MElectron", &ptr);

while MPhoton and MElectron are only container classes (derived from
TObject) storing values (no arrays, no pointers, only floats). The
Address is later on setup with B1/B2->SetAddress(..) before calling
Fill.

On Alpha the second call to T2->Branch craches...

Thanks,
Thomas.
