Summary: std::function(std::_Function_base) should use
std::addressof
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: n.fujita12@gmail.com
In std::_Function_base::_M_get_pointer, operator & is used to get a pointer of
the functor.
So, some callable objects which override operator & and they don't return their
pointer couldn't be held by std::function.
----
struct X {
void operator ()() const {
std::cerr << "X()\n";
}
float operator &() const {
return 1.2345;
}
};
int main() {
X x;
std::function<void ()> f(x);
return 0;
}
