[Bug c++/23764] New: Implicit conversion to a reference for an object broken

["rlyle at ritual dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to compile the following code on a FreeBSD 5.4 machine, using GCC 
4.0.1.... 

# 1 "Test.cpp"
# 0 "<built-in>"
# 1 "<command line>"
# 1 "Test.cpp"

class OutStream
{
public:
 OutStream();
};

inline OutStream & operator<<( OutStream & output, const int & value )
{

 return output;
}

class Client
{
public:
 OutStream send()
 {
  return OutStream();
 }
};

int main(int argc,char **argv)
{
 Client myclient;

 int x = 32;
 int y = 64;

 myclient.send() << x << y;
 return 0;
}

Produces the following output...
