[PATCH] D116750: [clang][lex] Keep references to `DirectoryLookup` objects up-to-date

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

> That's referring to the fact that once we allocate new `DirectoryLookup` with `SpecificBumpPtrAllocator`, address of that object won't change (unlike with `std::vector`). This means that we can take the address and use it without worrying about invalidation.

Ah, "stable" made me think of iteration order, but that's not what you meant. Makes sense, thanks!
