Subject: anno: Stop segmentation violation on `-number 0'.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/171ad462ce7582196f91f93f91f99fc60a21189e?hp=171ad462ce7582196f91f93f91f99fc60a21189e

anno: Stop segmentation violation on `-number 0'.

If atoi(3) returned zero, either because `0' was given or the number
could not be parsed, then the error message dereferenced an invalid
pointer.  Found when trying to increase coverage with check_exit.
