[Insight-users] Itk DiscreteGaussianImageFilter First-chance exception in Exception.exe (KERNEL32.DLL): 0xE06D7363

[ask ITK]

When I define my image as :

typedef unsigned char     PixelType;

typedef itk::Image< PixelType, 2 >   ImageType;
typedef ImageType::Pointer	ImagePtr ;

typedef itk::DiscreteGaussianImageFilter<ImageType,ImageType > 
GaussianFilterType ;

typedef GaussianFilterType::Pointer GaussianFilterPointer ;

I get this exception:

First-chance exception in Exception.exe (KERNEL32.DLL): 0xE06D7363:
Microsoft C++ Exception.

But when I changed the line
typedef  float     PixelType;

Everything ok, anyone as the same experience?
thanks!
