Details:

Octave stable (hg id: af302efce502) throws the following error


octave:1> x=1:10;
octave:2> x(minus(minus(end,1),1))
error: invalid use of 'end': may only be used to index existing value


The result should have been 8 ('end' should take the value 10).

In this other case, the result is correct.


octave:4> x(minus(end,1))
ans = 9
