ShapeUpgrade_UnifySameDomain class, an exception will be thrown.

I am using the ShapeUpgrade_UnifySameDomain class to modify the model. When processing using the following "shape.brep", the exception is raised in the build function. Is there any way to avoid this phenomenon?

[code]

try {
  ShapeUpgrade_UnifySameDomain unif( shape, Standard_True, Standard_True, Standard_True );
  unif.Build(); // <- exception
}
catch(...){
  // <- catch the exception
}

Best Regards.
