[PATCH] D43799: Don't allocate a header bellow address 0

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

If you can detect an underflow (or actually an overflow towards negative infinity), how hard is it to report it as an error, instead of not emitting a header without any message?
