--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Yup, this is ill-formed; no diagnostic required.(In reply to Andrew Pinski from
comment #1)
> Actually no this is invalid code at least according to the standard. Since
Yup, ill-formed; no diagnostic required. GCC has been getting smarter about
diagnosing these cases.
> Maybe just the use of N is not in the error message.
Yes, maybe a note pointing to the use of the name would be useful.
t8.cc:5:10: error: declaration of ‘N’ [-fpermissive]
enum { N }; // fails, redeclaration
^
t8.cc:1:11: error: changes meaning of ‘N’ from ‘const int N’ [-fpermissive]
const int N = 5;
^
t8.cc:4:13: note: used here
int Array[N]; // int[5]
^
Re-opening as a diagnostic bug.
