This one is kind of weird, because the code generated using obj2asm looks fine.
 Here's the test case:

    void main()
    {
        int i    = 5;
        int j    = 0;
        int* val = &i;

        asm
        {
            mov EAX, val;
            lock;
            mov EAX, [EAX];
            mov j, EAX;
        }
        printf( "%d\n", j );
    }

If the 'lock' instruction is commented out, the program works as expected.
