State-Changed-From-To: open-closed

State-Changed-When: Fri Mar 17 21:06:37 PST 1995
State-Changed-Why: 
Fixed. the grscan() utility function inside getgrent.c in libc would
slam head-first into a null pointer dereference when it hit the +:::
entry while processing a string of getgrent() calls. This means that
any programs that tried to scroll through the group database with
getgrent() would self-destruct after retrieving the last locally
stored group entry. grscan() is now smart enough to avoid the circumstances
that would lead to the null pointer dereference.
