A miss-unlocking bug

[ryancaicse]

Hi, it seems lock best->mutex is missed to be released before line 815. Should it be a bug?

@ryancaicse this is a bundled version of Zstandard. We don’t really maintain it. Most people who use SZ will install it with a system or spack provided Zstandard rather than this one. If the upstream Zstandard has this same bug fixed, we can look into updating the bundled version

@robertu94 Thank you for your reply. It seems they have fixed it.
