Overloading operators on a packed member reproducer
When overloading operators on a packed member, if the packing size is different
than the default size of the member, the namespace of the member is not
searched for the overloaded operator.
See attached example
Within a namespace NAMESPACE, a class CLASS formed with a packed enum ENUM.
When we apply an overloaded operator (in this case "<<"), the namespace of the
ENUM os not searched for the overloaded implementation. Instead the enum is
cast into an int and the int operator is used.
It is searched correctly is the class member is not packed, or if it is packed
to 32bits (cases a and c) as it does when using clang.
