[Osi] Pivot in OsiClpSimplexInterface

[Thomas Vincent]

Hi,

I'm trying to implement a parametric simplex for biobjective LPs using
OsiClpSimplexInterface.

Until now I have always set outStatus to 0 when calling the pivot method
and it seemed to work fine, except that sometimes I get the following error:

 ClpSimplex.cpp:7799: int ClpSimplex::pivot(): Assertion
`eq(solution_[sequenceOut_], lowerOut_)' failed.

How can I determine the value of outStatus before calling the pivot method?

Thank you
Regards,
Thomas
