_===========================================================_

Can you provide a reproducer of the crash ?

I was doing the following on a root file containing a chain:

TTree Comparison = (TTree) _file0->Get(“Comparison”)
Comparison->Draw(“Qeff:FrontFirstMod>>q0000(4000,-5,15,10000,0,0.05)”,“SampleDistance==0 && RemainingMat==3 && BackMod==0”)
.
.
.
Comparison->Draw(“Qeff:FrontFirstMod>>q2010(4000,-5,15,10000,0,0.05)”,“SampleDistance==20 && RemainingMat==3 && BackMod==10”)

q0000->Draw(“hist”); q0000->SetMarkerColor(kBlack); q0000->SetMarkerStyle(20)
.
.
.
q2010->Draw(“hist,same”); q2010->SetMarkerColor(kGreen+2); q2010->SetMarkerStyle(32)

I was then modified the canvas space (extremely slow) and the *** Break *** segmentation violation appear when I tried to save the canvas as a root file.

We need more details.

  • The file you with your tree
  • the exact sequence of commands reproducing the crash (as a C macro)
  • On which machine are you running ?
  • With which ROOT version ?
