[PATCH v2 05/11] bisect-run: verify_good: account for non-negative exit status

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some system never reports negative exit code at all, they reports them
as bigger-than-128 instead.  We take extra care for those systems in the
later check for normal 'do_bisect_run' loop.

Let's check it here, too.
