[MAC] gcc bug

[Mathieu Malaterre]

Hello,

	I tried to compiled VTK (http://vtk.org) using gcc on the MAC (G5), 
using the flag: -mpowerpc64

And it produces the error:

/Users/kitware/Dashboards/MyTests/VTK/Filtering/vtkPixel.cxx: In member
    function `virtual void vtkPixel::Clip(double, vtkDataArray*,
    vtkPointLocator*, vtkCellArray*, vtkPointData*, vtkPointData*,
vtkCellData*,
    long long int, vtkCellData*, int)':
/Users/kitware/Dashboards/MyTests/VTK/Filtering/vtkPixel.cxx:675: error:

    insn:

             (set (reg:CC 68 cr0)
                 (compare:CC (plus:DI (reg/v:DI 9 r9 [479])
                         (const_int -1 [0xffffffff]))
                     (const_int 0 [0x0])))
             (set (reg/v:DI 9 r9 [479])
                 (plus:DI (reg/v:DI 9 r9 [479])
                     (const_int -1 [0xffffffff])))
         ]) -1 (nil)
     (nil))
/Users/kitware/Dashboards/MyTests/VTK/Filtering/vtkPixel.cxx:675:
internal compiler error: in

Knowing that this bug only appear using -mpowerpc64, is this relevant to
this list, or is there a mac only gcc list ?

Thanks
Mathieu
