Re: Bug in Lilypond 2.8.5

[Mats Bengtsson]

I apologize if I sounded snippy. I just had a quick look at your email and
thought the error message looked very familiar to what you got due to a
bug that was present in certain versions, so I didn't read carefully enough
to realize that the dotted rhythm was the problem.
Actually, it turns out that \repeat tremolo won't create any dots at all
and I found a comment in the implementation about that this is something
to be done. However, you can play some tricks to get what you want:

\version "2.10.0"
\relative {< a' c es! a >8 \repeat "tremolo" 8 { < a c >32.. e32.. } |}
