--- Comment #4 from gcc-bugx at mailinator dot com 2012-06-04 08:21:54 UTC ---
Probably related error: this capture ignored on explicit instantiation.

struct A
{
    static void f() {}

    template <typename T>
    void foo()
    {
        [this] () { f(); };
    }
};

template void A::foo<int>();
