FillColor bug in root 6.22

boudry · February 18, 2021, 3:28pm

Bonjour,

I experience a segmentation violation when I try to touch the FillStyle in my objects (tried with TH1D and TPaveText). The following code & procedure lead to the crash:

h = new TH1D("h", "t", 10,0 ,10)
h->Fill(1)
h->SetFillStyle(2)
h->SetFillColor(2)
h->Draw()

First, the histogram is not filled as it should (it stays hollow, the TPaveText in was black).
Enabling the Editor (or the DrawPanel) on the Histogram,
and in the “Fill” section, clicking on the second square (“Fill style”)
results in the log output at the end of this post.

Any hints ?

Best regards,
Vincent Boudry.

Looking at it. I see that crash to when trying to access the fill menu of the GUI… weird…

   TH1D *h = new TH1D("h","t",10,0,10);
   h->SetBinContent(2,1);
   h->SetFillColor(2);
   h->SetFillStyle(3005);
   h->Draw("");
