vtkGraph FindVertex failure

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

I highly suspect that the issue lies somewhere more specific (might be related to http://www.vtk.org/Bug/view.php?id=13143), and therefore suspect it might cause for more issues in different components eventually. In any case, see the code below.

#include <vtkSmartPointer.h> #include <vtkDataSetAttributes.h> #include <vtkIntArray.h> #include <vtkMutableUndirectedGraph.h>

int main(int, char *[]) { vtkSmartPointer g = vtkSmartPointer::New();

vtkIntArray *pedigreeIds = vtkIntArray::New();

g->GetVertexData()->SetPedigreeIds(pedigreeIds);

g->AddVertex(vtkVariant(0));
g->AddVertex(vtkVariant(1));
g->AddVertex(vtkVariant(16));
g->AddVertex(vtkVariant(17));
g->AddVertex(vtkVariant(24));

std::cout << g->FindVertex(vtkVariant(24)) << std::endl;

return EXIT_SUCCESS;

}

On my PC (Visual Studio 2010 Pro; build debug x86) it will output -1. Removing any value (except for the last one, 24) will make it output values as expected.
