Bug #53483 indicated a problem in sqp which is track down to the C++ code of qp.cc

In line 99 qp uses a fixed tolerance for the search given by sqrt(eps). http://octave.org/doxygen/4.3/da/dbd/____qp_____8cc_source.html

This is a bug in qp and one would need to pass the tolerance as a parameter (or compute the correct tolerance for qp based on the arguments of sqp).
This bug is similar to feature request #43030
