Hello all,
I'm still hoping that someone out there will discover a cure to my
TClonesArray dilemma. Although adding the "new" call before the Branch
eliminates ROOT crashes with other data types (haven't checked but
simplest), the TClonesArray type still seems to crash ROOT during the
TTree::Fill() call.
I have a copy of example source at
ftp://ftp.npl.uiuc.edu/incoming/simple.zip
