Re: [Xen-devel] [PATCH v4 1/3] golang/xenlight: Don't try to marshall zero-length arrays in fromC

> The current fromC array code will do the "magic" casting and
> martialling even when num_foo variable is 0.  Go crashes when doing
> the cast.
> Only do array marshalling if the number of elements is non-zero;
> otherwise, leave the target pointer empty (nil for Go slices, NULL for
> C arrays).
