--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is one example where LLVM could be violating C aliasing rules:
void FoldingSetNodeID::AddPointer(const void *Ptr) {
  Bits.append(reinterpret_cast<unsigned *>(&Ptr),
              reinterpret_cast<unsigned *>(&Ptr+1));
}

There could be others.
