Don't rely on malloc to return NULL for zero size
We rely on samples being NULL if a dc have no samples. Its completely
legal for malloc to return a valid pointer to nowhere for zero sized
malloc, which you can't follow and read what its pointing at. Its only
viable to call free() on.
In other code, if samples is a valid pointer, we dereference it and look
at the first sample.
