What version of gradsdods are you using, on what platform? Did you
recompile it? If so against what library?

This could be either a bug or a library issue. I cannot reproduce it with
grads-1.9b4 on a fedora core 4.

To have a backtrace of the function calls leading to the segmentation
fault, you should start grads in a debugger, for example gdb:

[dumas at patoune tmp]$ gdb --quiet gradsdods
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) run
Starting program: /usr/bin/gradsdods
