Bug in CDL library v1.8

[Guest]

Dear sir/madam,

After extensive research why an IDL-script did not run on a Linux
machine, but did run on a Solaris machine, I found out that there is a
very very small bug (but annoyingly enough) that causes problems. I am
working with the Client Display Library (CDL) distributed by NOAO
(http://iraf.noao.edu/iraf/web/new_stuff/cdl.html). I have been using
v1.8. The bug is in the file cdl.c. On line 1084 it says in the original
file:
eps_print (psim, fp, pix, nx, nx, 8, 0);
^
while it should say
eps_print (psim, fp, pix, nx, ny, 8, 0);
^

This doesn't cause a segmentation fault on the Solaris machine I
installed it (though the created ps needs adjustment), but on the Linux
(RedHat FC 4) it does. Changing from nx to ny makes a perfect ps file.

Maybe it is a good idea to fix this bug in this release, or the upcoming.

Yours sincerely,
