commit dc76164c7693f57a6ded33a1344f2e8c1d6a0ee6
Author: Richard Levitte <levitte at openssl.org>
Date:   Thu Dec 8 11:16:37 2016 +0100

    In UI_OpenSSL's open(), generate an error on unknown errno
    
    TTY_get() sometimes surprises us with new errno values to determine if
    we have a controling terminal or not.  This generated error is a
    helpful tool to figure out that this was what happened and what the
    unknown value is.
