Attempts to call a member function in a local class nested in a generic lambda
nested in a function template results in an undefined symbol link error.
template <class>
void f() {
[](auto a) {
struct C {
static void g() {}
};
C::g();
}(0);
}
int main() {
f<void>();
}
$clang -std=c++14 link_error.cpp
