Date: | Wed, 28 Sep 2016 09:07:44 +0000 |
OK - I've spent quite a lot of the last week tracking this down. Short summary: commit e0af94bb8939bc6f4998db6294010baa77139092 (Replace C++ (in)equality checks with proper SCM syntax) is definitely the culprit. I've proven this by taking Gub back to its 2.19.18 state (with a few bugfix cherry picks to make it work on my system) and using 2.19.18 source on dev/philh. This produces a good output. Moving forward to 2.19.19 produces bad output. Moving back to commit "Issue 4343: quoteDuring music should be sent to midi file" produces good output. Moving forward one commit to the one identifed above produces bad output. I am therefore in no doubt that this is the issue. I've no idea why it only affect Windows, and only apparently with this issue. I think we have 2 options: revert the commit, or revert its use in simple-spacer.cc. I've not checked that the latter would work, but it seems likely, and if this looks the way forward I can burn some more CPU time and check with a further build that it works.

As reported by Karol and confirmed by Pierre, this code
\version "2.19.48" \transpose c c' { \repeat unfold 16 { e'8 a } R1*8 } \transpose c c' { \repeat unfold 16 { \grace dis'8 e' \grace gis8 a } R1*8 }
under Windows (at least 7 and 8) causes lots of programming error: mis-predicted force
and has the last staff flow into the margin.
Output at http://lilypond.1069038.n5.nabble.com/file/n188186/ttttttt.pdf
The first bad version is 2.19.19.
