The following code demonstrates a parse error. I've run this code through
several version of the g++ compiler (2.95.3, 3.1, 3.2.1, 3.2.3 and 3.3.2) and
all exhibit the same behaviour. To check the validity of the code I also ran it
through the Intel C++ compiler (v8.0) and it compiled fine.
$ cat g++-parser-bug.cc
#include <iostream>
using namespace std;
class Expr
{
public:
Expr() {}
friend Expr operator>(const Expr& lhs, const Expr& rhs) { return Expr(); }
friend ostream& operator<<(ostream& os, const Expr& e) { return os; }
};
int main()
{
cout << (Expr() > Expr()) << endl;
}

Confirmed. This is another instance of the parser bug described
on our bugs page. It is fixed in 3.4.0 and mainline, though.
