The code just clean the first member of array 'finsh_vm_stack', but it works well in the past years, 
            memset(&finsh_vm_stack[0], 0, sizeof(finsh_vm_stack[0]));
    Is it better to re-code as below, it will be more readable and robust:
            memset(&finsh_vm_stack[0], 0, sizeof(finsh_vm_stack));
