Follow-up Comment #4:

The error in 3.8.1 is actually a better result than silently overflowing and
returning a negative number for the number of elements.  On the other hand,
code that interacts with sparse matrices needs to be very sensitive to the
fact that numel() may overflow.  In a lot of sparse code it is better to look
at nnz rather than numel.  I made that change in spy.m on the stable branch in
this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/3994a1c2b994).  It
will be a parto of the 3.8.2 bug fix release, or you can just grab the spy.m
from the Mercurial repository and replace your local version with the new one.
