Turns out that compilation is fine if I compile with -mno-strict-align.
Maybe this is not a bug after all but simply changed semantics ?

You cannot really take the address of an elemenent of a packed struct on non
strict alignment targets as if you deference them, it will try to do an aligned
load which then fail as the alignment is wrong.

Does that mean this is really a glibc problem ?
In glibc, the problem occurs with an atomic_increment() on an element of a
packet structure.
