Not exactly with an empty struct we warn twice.
That is take:
struct MyClass{};
typedef struct MyClass MyClass;
MyClass Bar2( void ) __attribute__((warn_unused_result));
void Foo( void )
{
Bar2(); // warns twice
}
But the following only warns once:
struct MyClass{int t;};
typedef struct MyClass MyClass;
MyClass Bar2( void ) __attribute__((warn_unused_result));
void Foo( void )
{
Bar2();
}
The warning twice started with GCC 7.
