Array of pointers inside a __device__ function MMU fault

Hello everybody.

As title say i need to access items of two arrays from the pointers stored into another array:

unsigned long elements[2][4], *pointers[2];

pointers[0]=elements[0];
pointers[1]=elements[1];

These declaration and assignement are inside a device function.
But when i try to access items inside elements from pointers (for example with pointers[0][2]) i get an MMU fault.
Everything works fine if i try to access items inside elements from A and B declared in this way:

unsigned long elements[2][10], *A, *B;

A=elements[0];
B=elements[1];

but of course i don’t need this :-/

Am i missing something ?

Thank you for answers.

P.S.: if it could help, code is compiled on win7 x64 with vs2008 and executed on a GTX460.
