--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Better reduced testcase that shows what actually is happening in the older
GCCs:
struct cgraph_node;
struct tree_node;
typedef struct tree_node *tree;
struct cgraph_node *cgraph_node (tree);
void foo (int, const char *, ...) __attribute__((__format__(__gcc_diag__, 2,
3)));
