           Summary: [C++0x] no diagnostic for invalid use of auto with
                    array declarator
           Product: gcc
           Version: 4.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hstong@ca.ibm.com
              Host: powerpc64-unknown-linux-gnu
            Target: powerpc64-unknown-linux-gnu


A program is ill-formed if an array declarator is used to declare an entity
whose type contains the auto type specifier. A diagnostic is expected.

See subclause 8.3.4 [dcl.array] paragraph 1 in the 2011 FDIS.


### Self-contained source (a.cpp):
int v[1];
auto (*p)[1] = &v;


### Command to reproduce:
g++ -std=c++0x -Wall -W -pedantic -c a.cpp -o a.o


### Compiler output:
(No messages; return code 0)


### g++ -v output:
Using built-in specs.
