Commit 79b2366387dcd5f4ccae50eacf1ae06973f01d83 added the field `skip` to support unaligned reads, but set the `offset` field to a wrong value. This resulted in miscalculation of `remaining`, causing an assertion failure. The fix is to assign `offset` the correct value, but consider the `skip` value in the assertion.
