[Bug c++/42533] New: boost_concept_check.h - _SGIAssignableConcept broken the class self contains

["baiyang at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

for example, I have a class like this:

class MyClass
{
public: 
    MyClass() ...
    MyClass(IN const MyClass& rhs) ...
    MyClass& operator=(IN const MyClass& rhs)...

private:
    typedef std::map< string, MyClass > KEYTBL; // Self contains
    struct PROP {
       ...
       KEYTBL tblKeys;
       ...
    };

    typedef SMART_POINTER< PROP > HPROP;
    HPROP m_hProp;
};

As the example shown, If with out (early and msvc) the boost concept check,
then everything is perfect ok, Because C++ will try to instantiation the map
only when we need to use it. BUT the boost conept check (_SGIAssignableConcept)
just broken the c++ delay instantiation rule, so everything is broken here.
