           Summary: "no match" error when there is a match ...
           Product: gcc
           Version: 3.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: zolyfarkas@hotmail.com
                CC: gcc-bugs@gcc.gnu.org

Is this a bug ? Maybe ...

Here is the description ...
the following code :

class a
{
int i;
public:
a(){i=0;}
friend a operator+(a&, a&);
};

a operator+(a& a1, a& a2)
{
return a();
}

int main(void)
{
a res = a() + a();
return 0;
}
gives the following compilation error:
test.cc: In function `int main()':
test.cc:18: no match for `a + a' operator
test.cc:10: candidates are: a operator+(a&, a&)
test.cc:10:                 a operator+(a&, a&)

I shouldn't get this error ...

if i change the line with the error to the following : a res = (a&)a() + (a&)a
(); //it compiles
I should not need to do explicit casts is this case ...

I am working on a Solaris 9 sparc system

thanks
