I think stdin should be consumed line by line in order to make passing

row \$row; done" \necho two\n'; }
$ stdintest | dash
one
two
$ stdintest | bash
one
got row echo two

I think bash behaves "correct" here.
When I noticed the issue, I found this message with no response, but not
other threads. I believe, the following links may be useful for those
who will get this report in search engine results. It is a bug in dash
and latest released version does not contains its fix.
