>autofs-5.0.9 - fix reset flex scan buffer on init
>
>From: Ian Kent <ikent@redhat.com>
>
>If a scan results in an error the flex scan buffer is sometimes
>not properly reset for the next scan.
>
>This can result in an incorrect success return for a subsequent
>operation, such as a map re-read, for a master map line that's
>actually incorrect. Given the success return autofs tries to add
>a master map entry that doesn't have the needed information, such
>as the mount path, and a SEGV results.
