Bug in gcc?

Hello, all.
It seems to me I found a bug in gcc, but as it is rtems-provided cross-gcc, I
think it was better to ask here first.
I have the following code:
template <class TYPE> class sCmnd2DSPs {
public:
enum eSources {eDiscr=0, eRS1, eRS2,
eMB1, eMB2, eEth1, eEth2} __attribute__ ((packed));
struct {
eSources Source;
uchar Addr;
eCmndCodesDSPs Opcode;
TYPE Params; } __attribute__ ((packed));
...............
};
Everything works fine, but the field Source in the code above occupies 4
bytes, despite the packed request.
Now, if I take the enumeration declaration out of the class (put it above the
class declaration), then the Source field occupies 1 byte as required.
Should I report this to gcc list?
Thanks.
