Hi, Rene,
sorry for my insufficient information.
What I did are,
(1) open ROOT format file
(2) draw a 2d histogram
(3) define a graphical cut by the graphical editor.
(4) attempt to define one more graphical cut for another region of the
same histogram.
(5) segmentation violation.
I am running ROOT on RedHat Linux 8.0.
(gdb) run
