Hi Luis,
You do not specify the version of ROOT and the platform you are using.
Please send me your root file so that I can try to reproduce your problem.
Cheers,
Philippe

Subject: [ROOT] [Fwd: tree->Draw segmentation violation]
I sent this email twice days ago, but I don't know why, it doesn't get
into the mailling list... maybe it is because the attachments. Lets try to
solve this without them.

Hi Rooters
I've got a strange problem. I have a simple tree and need to plot one
variable with some cuts. I used to do
root> .x cuts.C
root>higgs->Draw("higgsmass",mc)
So far, it goes fine, but if I try to plot either the same plot
(with exactly the same command) or a new one, I got
a segmentation violation. The crash doen't occurs if I don't use cuts.
I could not send the tree (it is a small file), but I included a
print of it. The file cuts.C just
define what is MC (signal+background), signal and data.
Thanks for any help.
Luiz
The file "cuts.C" is below:
{
TCut signal = "strstr(channel,\"higs\")*scaling";
TCut data = "strstr(channel,\"data\")";
TCut backg = !data*"(!strstr(channel,\"higs\"))*scaling";
TCut mc = "(!strstr(channel,\"data\"))*scaling";
}
root [1] higgs->Print()
