I think the memory leak issue origined from QuadEdgeMesh,#include "itkQuadEdgeMesh.h"#include "itkRegularSphereMeshSource.h"typedef itk::QuadEdgeMesh< double, 3 > TMesh;typedef itk::RegularSphereMeshSource< TMesh > TSource;int main(int argc, char ** argv){  TSource::Pointer source = TSource::New();  source->Update();  TSource::Pointer source1 = TSource::New();  source1->SetResolution(5);  source1->Update();  TMesh::Pointer mesh = source->GetOutput();  mesh->Graft( source1->GetOutput());  return EXIT_SUCCESS;}It gives memory leak errors as well. wanlin
