    _______________________________________________________

Details:

In both 4.0.0 and hg tip, built with default options on x86-64, the following
code makes sparse matrices with a negative number of rows:


s = sparse(2e9, 1);
[s; s]
vertcat(s, s)
repmat(s, 2, 1)


Probably expected result: "error: out of memory or dimension too large for
Octave's index type" from each of the three commands.
