This is too vague an error report for me to be able to track it down.
I can't fix an error I can't reproduce. I would need to see the
script, simplified as much as possible but still reliably producing a
seg fault. I'd also want to see the complete text of a GrADS session,
and also perhaps some helpful output from gdb to see where the seg
fault is happening. Did you try Hoop's pre-compiled solaris builds
that we are distributing?

For GrADS 1.9, you need to link with an older version of the gd
library. Source can be downloaded here: ftp://grads.iges.org/grads/
Supplibs/1.8/src/gd-1.7.3.tar.Z
