Details:

Executing the command


  numel(spalloc(1e6,1e6,0))


returns -727379968 instead of 1e12. However, the following command produces
the correct result:


  prod(size(spalloc(1e6, 1e6)))



I could verify this behaviour using octave 3.4.3 (CentOS release 6.4 (final),
kernel 2.6.32-358.2.1.el6.x86_64) and octave 3.6.4 (Ubuntu 13.04, kernel
3.8.0-19-generic).
