Hi,
I am getting a segmentation fault error when I restore a .sav file
after SSH into a server. I basically do the following:
SSH to server
type 'IDL'
type 'restore something.sav'
type 'something'
This brings up a GUI (or was in the past). Everything was working
fine for a few weeks and now I get this error and IDL automatically
exits. I didn't do anything to the .sav file (and don't know what was
done by the author to create it). I asked the author, and they said
when they run it from my directory, it works fine.
Does anyone know what might have happened and what I might try to fix
this?
Thanks,
Howie

Howie, I got your email. Sorry for the late reply. Don't worry, nobody
knows everything. Anyways, I don't think it might be anything related
to exceed. Maybe there are people who use exceed X-window emulator on
this list, who have experianced similar problem? Did you try from
another windows box and see if it works? Did you do any tests?
I found these links on the web, I don't know if they will help in
solving your problem. I can't make any guess without knowing more.

something on restoring compiled IDL programs

I don't know if I helped you at all. Sorry.
Good luck,
