Here some more research on it, with extended test-cases:
control = {
\time 3/4
\repeat volta 2 { s2. }
\alternative { { s2. } { \time 4/4 s1 } }
s1
}
notes = {
\repeat volta 2 { R2. }
\alternative { { R2. } { R1 }
}
R1
}
%% Order matters
\score { \new Staff \with { instrumentName = "1" } << \control \notes >> }
\score { \new Staff \with { instrumentName = "2" } << \notes \control >> }
%% From commit-message of f372c695a52cf83ea00ff3be40acc542b4d46cbd
\new Staff \with { instrumentName = "3" }
\relative {
\partial 4
\repeat volta 4 { e'4 | c2 d2 | e2 f2 | }
\alternative { { g4 g g } { a a a a } }
a b2.
}
%% Accidental missing
\new Staff \with { instrumentName = "4" }
\relative {
\partial 4
\repeat volta 2 { d'4 | g1 | }
\alternative { { fis2. } { fis1 } }
g1
}
(1)
With released 2.18.2
Scores 1+2 look good, 3+4 not, score-4 misses the accidental in 2nd repeat.
No error/warning
(2)
With a build out of
commit f372c695a52cf83ea00ff3be40acc542b4d46cbd
Author: David Kastrup <d...@gnu.org>

Issue 355: \repeat bar lines get messed up
% the second repeat should start at the beginning of a bar, not
% continue from the incomplete bar in the first ending.
\version "2.17.30"
\new Staff \relative {
\partial 4
\repeat volta 4 { e' | c2 d2 | e2 f2 | }
\alternative { { g4 g g } { a a a a } }
a b2.
}
(first commit changing the previous behaviour)
Scores 1+2 look bad and emit barcheck-warnings and errors about not
spanned MultiMeasureRest
Score 3 looks good
Score 4 looks good as well, apart from the missing Accidental
(3)
With a build out of
commit b79db5deaf2159b569b1f9dab9c0fd59c3ff0533 (HEAD)
Author: David Kastrup <d...@gnu.org>
Date: Mon Jan 13 12:45:33 2014 +0100
Issue 3792: \time change under last \alternative does not persist
(first commit changing the previous behaviour)
Score 1 looks bad and emits barcheck-warnings and errors about not
spanned MultiMeasureRest
Score 2, 3, 4 look good (no warning or error)
Score 4 still misses the Accidental
This is still the behavior for current master.
I don't understand why score-1 is still bad and of course the
Accidental shouldn't be suppressed.
David I cc you, because you're the author of the mentioned patches,
any idea to improve?
Thanks,
Harm
