My fix to bug 13801 caused the compiler no longer to diagnose incompatible
refinements in nested scopes of the types of objects or functions with internal
linkage. (Fixing this involves adding a special "internal scope", like the
"external scope", which stores the full composite type information for entities
with internal linkage.) See also bug 21342.
Test 1:
static int (*a)[];
void f(void) { extern int (*a)[2]; }
void g(void) { extern int (*a)[3]; }
Test 2 (where the prototype information from the inner scope should be checked
against the old-style definition):
static int f(int (*)[]);
int g() { extern int f(int (*)[2]); }
static int f(a) int (*a)[3]; { return 0; }
Test 3:
static int (*a)[];
void f(void) { extern int (*a)[]; extern int (*a)[2]; }
extern int (*a)[3];

No, because there is no requirement for a diagnostic in these cases; they are all compile-time undefined behavior. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21343 ^ permalink raw reply [flat|nested] 7+ messages in thread
