Given the following sample code:

int main()
{
    int i;
    auto f = [=]()mutable->int*
    {
            return &i;
    };

    return 0;
}

The compiler reports "address of stack memory associated with local variable 'i' returned" for the 'i' in the lambda. That warning would be legitimate for a plain function but not for a lambda.

Note that this bug appears similar to bug #16548 but it is not the same. Here, the variable is captured by value rather than by reference.
