--- Comment #2 from Stephan Tolksdorf <st at quanttec dot com> ---
This regression from 4.8 seems to have been fixed on trunk but is still present
on the 4.9 branch. Could the fix be packported to 4.9?

Compiling the following simple snippet with "-std=c++11" produces a segfault
with 4.9: 

    template <typename... Ts> struct A {};
    struct B { B(A<int>); };
    B::B(A<int>) {}
