--- Comment #1 from ensadc at mailnesia dot com ---
Simplified:
----
template <typename G>
concept bool Graph = requires (G& g) {
add(g);
};
template <Graph T>
void add(T& g) {
};
class Directed_Graph_impl {};
int main() {
Directed_Graph_impl t;
add(t);
}
----
The problem seems to be that the instantiation of `add` requires the
instantiation of `Graph` concept, but the latter, in turn, requires the former.
This leads to an infinite recursion and eventually causes segfault.
