>Description:
In the attached code g++ invokes operator bool() of the template class before the invokation of operator<<() takes place.
This results in printing "1 in operator<<....." to stdout instead of printing "in operator<<..." twice.
#include <iostream>
using namespace std;
template <class T> struct Handle
{
Handle(T* p)
{}
operator bool() const { return true; }
friend ostream& operator<<(ostream& ostr, const Handle& r)
{
return ostr << "in operator<<(ostream&, const Handle&)";
}
};
struct Buggy
{
Buggy()
{}
};
typedef Handle<Buggy> Buggy_h;
struct BuggyCmp
{
bool operator()(const Buggy_h& b1, const Buggy_h& b2) const
{
cout << b1 << " " << b2 << endl;
return false;
}
};
int main()
{
BuggyCmp cmp;
cmp(new Buggy(), new Buggy());
}
