How can I avoid the warning "dynamic initialization in unreachable code"?

Question

I am writing a template function ^* similar to the following:

template <typename T, bool v> 
void foo(T t1) {
    /* common code */
    if (v) {
        int i = bar();
        /* ... */
        return;
    }
    else {
        /* ... */
    }
    /* more common code */
}

When I compile this and foocreate using vset to false, the compiler says:

warning: dynamic initialization in unreachable code

Now the code is unreachable due to the template argument; and that should be perfectly acceptable. How can I avoid or suppress this warning? I would rather not suppress such warnings at all.

Notes:

• I would prefer not to specialize differently for true and false, since there is a common code there, and I do not want to duplicate, as well as artificially create another function.
