Subject: Re: c++/9748: c++ using "operator = ( const Foo& )" when it *should* use "operator = ( int )"
Date: Tue, 18 Feb 2003 20:27:00 -0000	[thread overview]
Message-ID: <20030218202753.3444.qmail@sources.redhat.com> (raw)

Synopsis: c++ using "operator = ( const Foo& )" when it *should* use "operator = ( int )"

State-Changed-From-To: open->closed

State-Changed-Why:
    Not a bug.
    
    If you use the assignment for 
      Foo foo = 1;
    then a conversion constructor and a copy constructor needs
    to be accessible (the compiler is allowed to elide the
    temporary, though).
    
    In strict ISO mode, Intel's icc also agrees:
    tmp/g> icc -Xc -ansi x.cc
    x.cc(36): warning #734: "Foo::Foo(const Foo &)", required for copy that was eliminated, is inaccessible
              Foo foo = returnsInt();
                        ^
    
    What you quote about temporaries has nothing to do with
    this.
    
    W.
