Hm.

(BTW - forgot to say - igc_xfree instead of xfree too, but that
probably has nothing to do with it.)

Is that the same test case as before? I don't seems to get that.

Anyway. Eli can probably tell us how struct composition is used. If it
has to do with character composition, I think Eli once told that is
also something "new" (for me).

In what way does it fail? Can we look at the void * and check what it
is? p is_mps(x) for example and p *(struct igc_header *)
client_to_base(x), maybe?
