Summary0027305: Using undefined variables, which causes devide by zero
Descriptionin integration for #27190 there is incorrect using class math_FunctionSetRoot in
method static Standard_Boolean DecomposeResult(...)

          math_FunctionSetRoot aSRF(aF, aTol);
          aSRF.Perform(aF, aStartPoint);

The fields InfBounds and SupBounds are not initialized, but they are used in method Perform(...):
InvLengthMax(i) = 1. / Max((theSupBound(i) - theInfBound(i))/4, 1.e-9);
Steps To ReproduceNot required
Additional information

    0027300: Boolean operation produces invalid shape in terms of "bopargcheck" command
    
    1. Check, if value found by math_PSO algorithm cannot be precised by math_NewtonMinimum algorithm. In this case, we call math_PSO algorithm repeatedly, however, with other parameters.
    
    2. Some margin of edge tolerance value has been provided in IntTools_Tools class.
    
    3. Interface of math_NewtonMinimum class has been changed (method GetStatus() has been added).
    
    Correction of some test cases according to their new behavior.
