Hi,
Your macro works for me with the latest ROOT.

Subject: [ROOT] TImageDump error (1)

Hello ROOTers,

I wrote a short program which dumps a GIF image using TImageDump class. I found that the line "can->SetLeftMargin(0)" caused a runtime error. However Top/Bottom/Right work well. How can I avoid this error?

The error message is;
*** glibc detected *** double free or corruption (!prev): 0x08fa63c8 ***Aborted

ROOT version is 5.14 for SL 4.4

Sincerely

   can->SetRightMargin(0);
   can->SetBottomMargin(0);

   TH2D* hist = new TH2D("hist", "hist", 1, 0, 1, 1, 0, 1);    hist->Draw();

   TImageDump dump("test.gif");
   can->Paint();

   dump.Close();

   return 0;
