The dynamic analysis tests have uncovered a number of floating point exceptions, mainly divide by zero. This MR enables floating point exceptions if tests are built with a debug build type and the compiler is a gnu compiler. Safety guards have been added to classes that exhibited exceptions. TestAdjustLowerBoundForLogPlot.cxx - Tried to take log10 of negative number TestlinePlotDouble - inf and nan used in test. Disable exceptions vtkChart.cxx - guards to protect against zero divide vtkChartBox.cxx - guards to protect against zero divide vtkInteractiveArea.cxx - trying to take log10 of negative number vtkPiecewisePointHandleItem.cxx - protect against degenerate lines vtkAMRSliceFilter.cxx - protect against zero length vector vtkLagrangianBasicIntegrationModel.cxx - guards to protect against zero divide UnitTestMultiThreshold - disable exceptions for one test that uses Nan() vtkIntersectionPolyDataFilter.cxx - guard acos range vtkPCAStatistics.cx...
