Bug ID: 78216 Summary: Segfault when dealing with a parameter pack of member functions pointers Product: gcc Version: 6.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: michele.caini at gmail dot com Target Milestone: --- The following code causes an ICE (segfault): template<typename...> struct S; template<typename R, typename... A, typename... T> struct S<R(A...), T...> { template<R(T::* ...M)(A...)> void f() {} }; struct A { void f() {} }; struct B { void f() {} }; int main() { S<void(void), A, B> s; s.f<&A::f, &B::f>(); } GCC 7 is affected by a similar problem (ICE with no segfault).
