Of course. Your grammar fails for "no content". If empty content is ok,
change the grammar.

Note that in this exact case you would have saved everyone time by
letting your self-contained sample SHOW that you want to parse "only
comments" with success.

E.g. Failing testcase
<http://coliru.stacked-crooked.com/a/e2e72142cfcbe071>

Or perhaps even with debug enabled
<http://coliru.stacked-crooked.com/a/b8303e7d827d7531>

In which case the simplest thing that makes the test pass would be to
replace the grammar with `qi::eps`, but I suppose this could be closer
to what you expect:

                run_app = - symbol;       

Make the symbol optional, so that if you don't parse one, it doesn't
fail: http://coliru.stacked-crooked.com/a/1518a0e0d5adde23

Output

    Parsing SUCCESS.
    Parsing SUCCESS.
    Parsing SUCCESS.
    Parsing SUCCESS.

    Parsing SUCCESS.
    Parsing SUCCESS.
