Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- The warning here is intentional -- as noted, a [static 1] array can be as small as a single element. The warning is designed to help detect stronger assumptions inadvertently made by the function definition. (The compiler makes no analysis to see how the function is being called; it could if the function were declared static but but without full LTO it can't for an extern function.) The recommended annotation to indicate that a pointer argument must not be null is attribute nonnull.
