Test failure when Data/Sample is not available

[havardAasen]

This relates to stable/0.108 branch, tested with CoinUtils 2.11.10 and as the title says, without the directory Data.

We begin with a segfault in

Osi/Osi/src/Osi/OsiColCut.hpp

Line 248 in f705b23

bool OsiColCut::feasible(const OsiSolverInterface &im) const

This is fixed with commit 5c401b5, I'm not sure if it is a underlying problem that's still unresolved by this patch, it's obvious that the tests will fail, though I haven't looked at why column information is not available.

Whit the patch applied, the unit tests completes with 12 unexpected error

Tests completed with 12 unexpected errors

As can be seen from the log, 4 tests fails because it can't read ../../Data/Sample/exmip1.mps, 3 tests fails with the patch I mentioned earlier, column information is not available.

I haven't looked at why the last 5 tests fails, however, of these 5 failed tests, only 1 still fails when Data/Sample is available.

---

If I run the tests when Data/Sample/exmip1.mps is available I get 1 error.

This error was fixed by applying this commit 192b006

@tkralphs This sounds exactly like the same problem we are facing for conda
conda-forge/coin-or-osi-feedstock#15

What should we do here?
