qp() in Octave 3.0.0 returns result egregiously violating input constraints

Put a keyboard command in qp.m before line 273, i.e. right before the
"__qp__" call and check:
norm(A*x0-b)  
(which should be small)
all(Ain*x0 > bin-tol)   
which should be 1 (these are all inequality constraints in the form
required by __qp__)
