offset wire_closed_inside_0_025 G4
   offset wire_closed_inside_0_075 G4

The problem can be fixed by correction of MAT2d_Tool2d::TrimBisector(...) method (MAT2d_Tool2d.cxx, line 496 on remotes/origin/IR-2018-01-26 GIT-branch).

E.g. current code

  if (param > bisector->BasisCurve()->LastParameter()) {
    param = bisector->BasisCurve()->LastParameter();
  }

should be replaced with

  if (param > bisector->LastParameter()) {
    param = bisector->LastParameter();
  }

This way has been detected while analyzing the problem in the issue 0029115. However, this solution is not a good fix and leads to additional regressions. But please take into account this message when debugging these tests.
