When I made the first report, I had no idea what was causing it. All I knew was that replacing the quadruplet with a rest made it problem disappear, so it looked to me as though that was the problem. You, with your broader knowledge of LilyPond bugs,

I wish that people would stop assuming that I know what I'm doing. For bugs, I simply spend five minutes experimenting. For example, starting from this:

\relative c' {
  \key d \minor
  \time 12/16
\times 3/4 {g'8 f8} f4 \pitchedTrill f8. \startTrillSpan ges f8\stopTrillSpan |
}

I did the following.

1)  Is there a bug?  ...compile, view... ok, there's no flat on the ges.

2)  The \times looks irrelevant; what happens if I replace it by g4 f4?
... compile, view... ok, bug still present.

3) What about the \time? That looks really silly. Let's remove that, and change all the durations to 4.
... compile, view... ok, bug still present.

4)  Key signature?  remove, compile, view.  Bug still present.

5) What about removing the \pitchedTrill ? remove, compile, view... ah, of course. Bug not present, but neither is the ges, so that was silly. Let's put the \pitchedTrill back in there.


At no point did my supposed knowledge of lilypond come into play. All I ever do is experiment. I mean, I don't even know how \pitchedTrill and \spanner stuff works, as was evident from my trying to deleting them.

Oh, also by "remove", I mean "comment out, compile to test, and only actually delete the item once I've verified that I still see a bug when it's commented out". I learned this trick the hard way.

Cheers,
