% \partcombine should have produced a combined staff containing d'1 in % the first bar, f'1 in the second and 3rd bars, and <f' d'>1 chords in % the next 2 bars. However, it seems to interact badly with \tag, and % the output has a missing f1' in the second bar, a stray rest in the % 3rd bar, and a missing d'1 in the 4th bar. The first and last bars % appear to be OK. (See attached .pdf file.) % % Removing the \removeWithTag line reveals that \partcombine has indeed % combined the notes correctly, but apparently left the tags on the % wrong notes, so that \removeWithTag deleted the wrong objects. % % Arguably, using \tag with \partcombine is a bad idea, since it can % easily result in constructs that are probably not representable in a % way that would make a subsequent \removeWithTag work correctly, but % Lilypond should at least give a warning and/or reject such input % instead of generating wrong output.
