NOTE: this is a moderately non-sensical snippet reduced from an actual chunk of
code which does make more sense

$cat a.cc
// compile with clang++ -std=c++11
template <int>
class A {

  struct B {};

  void Foobar() {
    [](int d) {
      B *e(d);
      [e, d]() {
        int i = d;

$clang++ -std=c++11
clang: llvm/tools/clang/lib/AST/../../include/clang/AST/Type.h:547: const
clang::ExtQualsTypeCommonBase* clang::QualType::getCommonPtr() const: Assertion
`!isNull() && "Cannot retrieve a NULL type pointer"' failed.
