We don't use malloc and free in Rockbox. Allocate whatever memory you
need with static

Codecs uses IRAM and the Rockbox core itself uses IRAM. You're probably
trying to link
the Wavpack library to the Rockbox core, which will not work, since the
IRAM usage of both will be more than the core itself is allowed to use
(32kb i think).

Like I said above, the Wavpack code uses IRAM in places.
