Hi Andrej,

Thanks for noting this problem.  The proper fix is pending being checked-in
the CVS repository.  Note that your proposed fix is incomplete since
fDirectory can also be null.

Cheers,
Philippe.

Hi,

there is a bug in rootcvs in TTree::Fill function. Fill crashes if there
is no TFile used. The line tree/src/TTree.cxx:2000

	if (!fDirectory) return nbytes;

should be modified to

	if (!fDirectory->GetFile()) return nbytes;

Andrej
