Hi,
If I analyse a tree and do, for example
tree->Draw(“px>>PX(512,-10,10)”);
and then
tree->Draw(“px>>PX(512,-10,10”,“py>0”);
I will get the following when trying to use PX
root [10] PX
*** Break *** segmentation violation

I get the same error independant of tree and its structure etc. It is when I try to reuse a histogram with new cuts applied. If I do a histo->Delete() between I don’t have any problems. My question is, is this normal and just because I’m a bit sloppy when using
cint or do I have a somewhat defect root installation (SL 4.3, x84_64, gcc 3.4.5, root 5.14)?
kind regards
Joa
