I cannot repeat this error on my local installation. The stepper and the
'runner' produce the same output. 

(Of course, if I delete the "sample.dat" file, BOTh the stepper AND the
runner signal the same error, namely the one you mention.) =

Well, just to add to the confusion, I just tried to reproduce the error
again in my machine, and now both the stepper and the runner work fine! I
swear that wasn't the case before, and I didn't do anything different this
time. Chalk it up to the mysteries of computing, I guess.
