The reason is that the current implementation of malloc_zone for linux
(src/shims/malloc_zone.h) is just a dummy implementation and returns always a
null-pointer. Therefore, this assertion will always fail.
The current dummy implementation just dispatches the zone_malloc calls to the
normal malloc routine. The attached "patch" circumvents the problem with the
assertion by allocating a zone and returning a pointer to it. The behavior of
the zone_malloc remains the same.
