Issue details

I'm getting an Empty / bogus instruction is invalid but i'm pretty sure its ok.

Steps to reproduce/test case

This is part of my dockerfile. This runs correctly in docker.

RUN apk update \
  # psycopg2 dependencies
  && apk add --virtual build-deps gcc python3-dev musl-dev \
  && apk add postgresql-dev \

I have multiple lines after this one that start with && and they do not have this error.
