[Bug objc/48187] New: infinite errors with misplaced [ in @interface definition

           Summary: infinite errors with misplaced [ in @interface
                    definition
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: objc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: cjwl@objc.net


While parsing the code:

@interface InfiniteErrors { ]} @end


The compiler will repeatedly and indefinitely log the error:

error: expected specifier-qualifier-list before ']' token

This occurs in 4.2.1 also, so I believe it is an old problem, searched for an
existing report but don't see anything similar.
