<pre>We have a template class containing a lambda which itself contains an inner
class.
Both inner structures -- the lambda and its inner class -- depdend on the
template parameter of the outer class.
Instantiation of this gives the assertion failure in the summary.
### SOURCE: cat t.cc
template <class R> struct S {
S(R x1) {
[] (R x2) -> void {
struct A {
R x3;
A(R x4) : x3(x4) {}
};
A a(x2);
}(x1);
}
};
S<int> t (0);
int main() { }
