Unexported struct fields which are pointers are not deep copied

Reproducible Example

Description

Refer to the example above.

type Address struct {
    Street string
    City   string
}

type Person struct {
    Name string
    Age  int
    addr *Address
}

If a struct has an unexported field and if it is a pointer then DeepCopy of this unexported pointer does not happen.
