Bug ID: 91141
Summary: Can't use class members inside conditional noexcept
specifier
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: brickmen75 at gmail dot com
Target Milestone: ---
There is minimal example of code that deny to compile:
--------------------
template <class T>
class widget {
public:
void swap(widget& rhs) noexcept(noexcept(std::swap(t, rhs.t))) {
std::swap(t, rhs.t);
}
private:
T t;
};
int main() {
widget<int> w1, w2;
w1.swap(w2);
}
--------------------
Seems like gcc forbids use of class members inside conditional noexcept
specifier. Simple workaround is to use this-> along with class members.
