local memory conflict?

Just experienced a bizarre problem. I can't past the entire code to confuse you. The program is like this conceptually:

 

struct st_a{

    ...

    int3 vInA;

    ...

    int num;

};

 

struct st_b{

    ...

    float3 vInB;

    ...

}

 

__kernel void MyKernel()

{

    __local struct st_a A;

    __local struct st_b B;

    A.vInA = (int3)0;

    B.vInB = (float3).6f;

    // OMG, A.vInA is now very big numbers!!!

    ...

}

 

I only launched one work item, so there is no write conflict.

 

Does anybody have any suggestions?

 

Thank you in advance!
