[vtkusers] Known limits on marching cubes ?

Hi vtkusers,

I'm trying to contour stacks of X images using VtkMarchingCubes.
The images represent a block of 512 x 512 x 128 8-bit images.

My pipeline is basic : 
* vtkImageImporter (using a pointer on raw data without saving data) : importer->SetImportVoidPointer(wk1, 0);
* vtkMarchingCubes (with one isovalue)
* vtkIVWriter

My problem is I get several error messages :
ERROR:In d:?nightly?vtk?common?vtkIntArray.cxx, line 216
vtkIntArray(0x008C5720): Cannot allocate memory

But it works fine for a smaller set of images (128 x 128 x 128, 8 bits).

I suppose I overtake a memory limit somewhere.

Does anybody have experienced such problems ?
I would be interested in knowing how big images processed by vtkMarchingCubes can be.
