      Description

      Fuzz testing found some crashes in the LZO text scanner.

      I can reproduce easily with the fuzz test: https://gerrit.cloudera.org/#/c/3448/

      They are mostly hitting this DCHECK in:

      void Status::AddDetail(const std::string& msg) {
        DCHECK(msg_ != NULL);
      

      It looks like the crashes were introduced when switching to the new status API.
