And you are running on a Sparc Ultra, right? Since FPS (our IDL
reseller) don't really seem to be aware that this is a known problem
and that there is a patch for it, I'll chip in with the answer.
4.0.1c fixes it.

It took me more than a week of phone calls to FPS and to Sun to find
this out, only to find out

a) That IDL is officially not supported on any version of Solaris
after 2.3. (!)

b) They have a fix in the form of 4.0.1c anyway.

It seems a rather inconsistent position to take, but who am I, a mere
user to complain?

Yeah, thanks, I got it! This problem is known (I was told it happens on
Sparc Ultras only) and the update to 4.0.1c fixes it.

This problem doews not occur with !VERSION.RELEASE = '4.0.1c'
running Solaris 2.5.1

idl>help,/str,!version
** Structure !VERSION, 4 tags, length=32:
ARCH STRING 'sparc'
OS STRING 'sunos'
OS_FAMILY STRING 'unix'
RELEASE STRING '4.0.1c'
idl>print,0.0/0.0
NaN
% Program caused arithmetic error: Floating illegal operand

I suggest downloading the latest version of IDL as a start...
