Cloning TH3F

ROOT
1

Dear root supporters,

Is it possible to read a TH3F histogram from file and close the file?
I try it with different methods (new, Copy, Clone) but I get “segmentation violation” in all cases when trying to access the histogram after file closure (see attached scripts).

Thanks in advance,
Dmitry.

in test2.C (at beginning) add the line

TH1::AddDirectory(kFALSE):For explanation, read the chapter “Object Ownership” in the Users Guide.
