--- Comment #1 from redi at gcc dot gnu dot org 2010-08-23 13:17 ---
The summary seems backwards: the conversion shouldn't generate operator==,
instead using operator== should trigger the conversion, but fails to when the
conversion operator is a template.
Strangely, adding a non-template conversion operator causes template argument
deduction to succeed, even though the non-template operator isn't used
e.g.
#include iostream
struct null {
null() {}
templateclass T
operator T*() const {
return 0;
}
templateclass C, class T
operator T C::*() const {
return 0;
}
private:
operator double*() const; // ???
null(const null);
null operator=(const null);
void operator() const;
};
static struct null null;
int main() {
int* ptr = null;
std::cout (ptr == null) , (ptr != null);
return 0;
}
