I was wrong about it running in earlier versions of IDL.
It fails reliably in all of them if you run the program
enough times (2).

According to RSI this is listed as a known "defect",
but I am apparently the first person in recorded history
to run into it in practice. Not much motivation to get to
the bottom of it, as I understand it, unless more people
complain. I guess I'm talking to all three of you who
have downloaded the programs that go with my book. :-)

Cheers,

David
