Constraints not met

Rate this Message:
Dear Octave Team,
I am a new user of Octave and am using this to optimise a series of
small qp problems. I have encountered some problems while using the qp
program. I used octave to run the attached optimisation problem and
received an output with info = 3, however, on analysing the data I
noticed that the solution was not convergent and the constraints not
met.
I am attaching the problem file and the output file. Is this a bug? Any
help is most appreciated.
