                    virt-specifier
           Product: gcc

            Status: UNCONFIRMED

GCC failed at virtual function with "override"
 trailing return type name, followed by override virt-specifier.

Following code should be well-formed.

struct override { } ;

struct Base
{
    virtual auto f() -> override ; 
} ;

struct Derived : Base
{
// GCC issues error: two or more data types in declaration of 'type name'
    auto f() -> override override ;
} ;
