Thanks! I believe it fixes a long tail crash.



================
Comment at: clang/unittests/Lex/LexerTest.cpp:665
+TEST_F(LexerTest, BrokenStringLiteral) {
+  const llvm::StringLiteral Source = R"cpp("\N")cpp";
+  // Make sure this isn't crashing.
----------------
nit: I'd probably use a clang lit test

```
auto nocrash = L"\N";
```

but up to you.
