Consider the following program:
m>
enum X { a = 1 };
enum Y { b = 1 } __attribute__((packed));
int main()
{
using namespace std;
cout << "default: " << sizeof(enum X) << endl;
cout << "with attribute: " << sizeof(enum Y) << endl;
}
The C++ compiler accepts this. However, the attribute on enum Y is ignored. As
running this program
shows, the size of enum Y is the same as the size of enum X.
Note that the test suite contains a test to make sure that an attribute in this
position is accepted.
(parse/parse3.C) We just failed to make sure that the attribute really did anything.
