Following code should compile:
class X
{
public:
X()
{
}
private:
X( const X& );
X& operator=( const X& );
};
void f( const X& )
{
}
int
main()
{
f( X() );
return 0;
}

For instance, consider the following code: class A { public: A(); private: A(const A&); // private copy ctor }; A makeA(void); void foo(const A&); void bar(void) { foo(A()); // error, copy ctor is not accessible foo(makeA()); // error, copy ctor is not accessible A a1; foo(a1); // OK, a1 is a lvalue } -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17184 ^ permalink raw reply [flat|nested] 3+ messages in thread
