[vlc-devel] atomic_fetch_add for refcounting harmful ?

We use atomic_* functions for refcounting, (input_item_Hold)
and I believe we somehow suffer the same issue as CVE2016_0728
as atomic_fetch_add does not provide any way to check for overflow
before adding.

Any comments and solutions (outside of using lock and checking max value) ?
