      Came across a problem with decoding pointers.
      Example of code to reproduce common issue:

      package main
      
      import (
      	"github.com/mongodb/mongo-go-driver/bson"
      	"log"
      )
      
      type TestStruct struct {
      	TestValue *string `bson:"test_value,omitempty"`
      }
      
      func main() {
      	testString := "test value goes here"
      	t := TestStruct{
      		TestValue: &testString,
      	}
      	data, err := bson.Marshal(t)
      	if err != nil {
      		log.Fatalf("Failed to marshal. Error: %v", err)
      	}
      	unt := TestStruct{}
      	err = bson.Unmarshal(data, &unt)
      	if err != nil {
      		log.Fatalf("Failed to unmarshal. Error: %v", err)
      	}
      	log.Printf("Result: %+v")
      	if unt.TestValue == nil {
      		return
      	}
      	log.Printf("Contained string: %+v", *unt.TestValue)
      }
      

      Code like the one above gives error like:

      reflect.Value.Addr of unaddressable value
