Forwarding to the bug list. Yes, if I'd make your code available to the
developers.

Best,

Hi,
I'm trying to paginate my score nicely and the automatic paging isn't good
enough. So I'm doing all the page breaks manually -- and a certain
situation is causing an assertion failure on compilation:

<< Snippet of output:

....

MIDI output to `BeiMannernScore.mid'...

Finding the ideal number of pages...

Fitting music on 9 or 10 pages...

This application has requested the Runtime to terminate it in an unusual
way.

Please contact the application's support team for more information.

Assertion failed!

Program: C:\Program Files (x86)\LilyPond\usr\bin\lilypond.exe

File:
/home/gub/NewGub/gub/target/mingw/src/lilypond-git.sv.gnu.org--lilypond.git-release-unstable/lily/page-breaking.cc,
Line 1180

Expression: ret <= cached_line_details_.size ()

Exited with return code 3.

The problem occurs with the page break on a specific bar. For now I've done
the obvious thing and gone with a working state -- it's not critical.


Happy to push the code up to a Gist for anyone that wishes to debug the
issue. Let me know.


(This is apparently not happening if I build on Linux, only in Windows).
