[clangd] Crash at clang::Decl::getLocation() DeclBase.h 442:47

[henryhchchc]

Opening a C++ file with the following content leads to a crash in clangd.

namespace rdar13395022 {
  struct MoveOnly ;

  void test(MoveOnly mo) {
    auto &&list1 = {mo};
    MoveOnly (&&list2)[1] = {mo};
    std::initializer_list<MoveOnly> &&list3 = {};
    MoveOnly (&&list4)[1] = {};
  }
}

Opening a C++ file with the following content leads to a crash in clangd. Compiling this file with clang does not lead to a crash.

namespace std {
  typedef decltype(sizeof(int)) size_t;

  template <typename E>
  struct initializer_list
  {
    const E *p;
    size_t n;
    initializer_list(const E *p, size_t n) : p(p), n(n) {}
  };

  struct string {
    string(const char *);
  };

  template<typename A, typename B>
  struct pair {
    pair(const A&, const B&);
  };
}

Opening a C++ file with the following content leads to a crash in clangd. Compiling this file with clang does not lead to a crash.

namespace std {
  typedef decltype(sizeof(int)) size_t;

  template <typename E>
  struct initializer_list
  {
    const E *p;
    size_t n;
    initializer_list(const E *p, size_t n) : p(p), n(n) {}
  };

  struct string {
    string(const char *);
  };

  template<typename A, typename B>
  struct pair {
    pair(const A&, const B&);
  };
}
