<div>
<pre>Compiler crashes with the following, minimal example:
template<typename Func>
struct Base: Func {
Base(Func func): Func{func} {}
template<typename... Args>
auto operator()(Args... args)
-> decltype(Func::operator()(args...), void()) {
Func::operator()(args...);
}
};
int main() {
auto l = [](auto &&) {};
Base<decltype(l)> mixin{l};
mixin(0);
}
Note that it works as expected using the following lambda:
auto l = [](int) {};</pre>
