What system are you using?

What version of Octave?

This does not appear to be a problem with 2.1.50 or the current CVS
sources on a Debian system.

Perhaps the problem is due to an old bug in the C or C++ library on
that system that causes binary reads to report the wrong number of
bytes or the wrong status at EOF (I can't remember the precise details
of the bug, just that there was one -- maybe someone else remembers
more can provide additional information).
