--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Thanks.
Here is another one:

trippels@gcc2-power8 llvm_build % cat SelectionDAG.ii
struct A;
__attribute__((noreturn)) void report_fatal_error(A);
struct A {
  enum NodeKind {};
  struct Child {
    int cString;
    int decUI;
  } LHS;
  Child RHS;
  NodeKind LHSKind;
  NodeKind RHSKind;
  void m_fn1() const;
  A(char *);
  A(int) : RHSKind() { LHS.decUI = 0; }
  A m_fn2(const A &) const;
};
A A::m_fn2(const A &p1) const {
  int a, b;
  a = LHSKind == 0;
  if (a)
    return 0;
  b = LHSKind == 1;
  if (b)
    return p1;
  m_fn1();
}
inline A operator+(const A &p1, const A &p2) { return p1.m_fn2(p2); }
void checkAddrSpaceIsValidForLibcall(int) {
  A c = "" + A(0);
  report_fatal_error(c);
}
void getMemcpy() { checkAddrSpaceIsValidForLibcall(0); }
