This PR addressed: * IR for multiple RHS in Ma57 * A few integer overflows when reporting the global number of variables. I also enabled the compiler flag `-ftrapv` to...
strongly recommended. for best performance, this should be done for multiple rhs along the lines of @BarrySmith 's comment from PR #58

I whant to solve some task in lp format.
garbage input point from julia (nans, denormalized numbers) creates an havoc in pips-nlp.
**Behavior** The NLP PIPS-NLP solver does not converge for some extreme-scale problems (thousands+ scenarios and million+ variables/constraints). The manifestation of this issue includes any of the following: 1. PIPS-NLP returns...
I have found and fixed two issues. The first issue is that member variable ``xDiag`` is not initialized and can potentially be undefined if ``nxlow + nxupp == 0`` (that...
