in a program I write some root objects to a file with TObject::Write() and
try to read them back with TObject::Read(), but get segmentation faults on
the Read statement. Any ideas welcome.
Ulrich
TFile rfile("test.root" , "new");
rfile.SetCompressionLevel(1);
md->annotation->Write("annotation");
...
TFile rfile("test.root", "read");
if (rfile.IsOpen()){
md = new MeasurementData(); // contains default constructors for root obj
md->annotation->Read("annotation"); // segfault, trace back:
