Following observed:
thread '<unnamed>' panicked at library/core/src/panicking.rs:156:5:
unsafe precondition(s) violated: slice::from_raw_parts requires the pointer to be aligned and non-null, and the total size of the slice not to exceed `isize::MAX`

Reason, according to the docs:
"data must be non-null and aligned even for
zero-length slices."
Add check to prevent hitting this case.
