I have to agree with the Wanderer. It's not Voldemort's use, but any use of the Killing Curse. Here, check the Harry Potter Lexicon, which is accurate and detailed enough that Rowling consulted it while writing the later books. To cite its third point, "Harry is the only known person to survive the Killing Curse (esp. PS1, GF14, also GF34). "
