Summary0031865: Mesh - triangulation fails with large deflection values due to unhandled Standard_OutOfRange, BRepMesh_PairOfIndex::Append()
DescriptionAttached face cannot be triangulated due to unhandled Standard_OutOfRange, BRepMesh_PairOfIndex::Append() exception.

The issue is reproducible since OCCT 7.4.0 (earlier versions produced 49 or 51 triangles, which is probably exhaustive but not empty)
