OCC 6.5.1 regression inside BRepExtrema_DistShapeShape

Dear OCC Team,

Please, find complete explanation and correction in enclosed file

OCC Version : 6.5.1
OS : All platforms
Package : Modeling Algorithms\TKTopAlgo.dll
Source \OpenCASCADE6.5.1\ros\src\BRepExtrema\BRepExtrema_DistanceSS.cxx

Thanks you for delivering full source code. Simple Bugs can be found and corrected rapidly
even if OCC 6.5.1 is harder to compile than before due to great 3rd party (TBB for ex) making more complex dependencies (version, os, lib, dll, inc)

Best regards,
