It ends up making two similar types, [N]uint8 of both alg and noalg varieties. Comparsions between the two then don't come out equal when they should. In particular, the type *[N]uint8 has an Elem pointer which must point to one of the above two types; it can't point to both. Thus allocating a *[N]uint8 and dereferencing it might be a different type than a [N]uint8. The fix is easy. Making a small test for this is really hard. It requires that both a argless defer and the test be imported by a common parent package. This is why a main binary doesn't see this issue, but a test does (as Agniva noticed), because there's a wrapper package that imports both the test and the defer. Types like [N]uint8 don't really need to be marked noalg anyway, as the generated code (if any) will be shared among all vanilla memory types of the same size.
