Beware of structure padding leaving holes.

Hmm, I tried..
struct foo {
uint8_t a;
uint8_t b;
uint8_t c;
uint8_t d;
uint8_t e;
} __attribute__ ((packed)) abc = {
1,
2,
3,
4,
5
};
but there is no change in behaviour.
I would not expect GCC to pad [too much] on AVR anyway because the processor
doesn't require aligned access.
Because i haven't got a running system to test it on, i can only infer
things at a distance. I can't see any bugs in the supplied code. Maybe
it's interaction or something being overwritten by another part of your
system?
