Struct cudaMemset failure Memory size or pointer value too large to fit in 32 bit

Hi,

I get an error, when I try to initialize the following structure:

typedef struct Abstraction
{
// Abstraction variables
unsigned __int64 OriginalSumSDV[22100];
int OriginalGroupNumber[22100];
unsigned __int64 GroupSumSDV[1756];
int GroupValue[1756];
int GroupSize[1756];
int Groups;
} *PABSTRACTION;

PABSTRACTION dFA;

cudaMalloc( (void **) &dFA, sizeof(Abstraction) );

cudaMemset( &dFA, 0, sizeof(Abstraction) ); // This gives an error

Memory size or pointer value too large to fit in 32 bit

Can I not use __int64 types in structs, since it works fine, when its just an __int64 pointer.

Any help in locating and correcting the problem is much appreciated.

I managed to solve it :)
