As I noted in the src commit, I think r318161 addresses the issue
(also identified by Coverity as CID: 1374641). Basically, buf2 was in
scope for the conditional as stack memory, `path` took the address
buf2 and used it out of scope (which may have triggered the compiler
to optimize/evaluate the code incorrectly since the case seemed
impossible).
Thanks,
