I have tried all three and none of those worked: got the same segmentation
fault error.

It works fine and I got a figure showing the line thickness in colors with
difference line numbers.

It is a basic and simple plot. The fact that it crashes for line options
puzzles me.  It may be a set-up issue when installing ferret.  I am just
wondering if anyone else has encountered the same problem before I send an
e-mail to the system adm.

Thanks,
