I've heard through the usually reliable grapevine that
this is a discovered and documented bug in the Sun version
of IDL 5.4. But even though a number of people have spent 
a lot of time looking at it, no one so far has been able
to pin-point the problem. It continues to be worked on.

The problem is made more difficult by the the use of
several different library routines from different vendors
in the affected code. The fact that the problem does not
appear in other UNIX versions suggests a problem in
a Sun library routine, but this is by no means
certain. RSI is working with Sun to identify and fix
the problem as soon as possible.

I'll let you know if I hear anything else.
