Hello denemo friends,
I'm using 1.2.4. on a windows computer.
I added a dynamics staff and then tried typesetting and I got this message:
Assertion Failed
Program C:\Program Files (x86)\usr\bin\lilypond-windows.exe
File:
/home/jjbenham/public_html/gub/target/mingw/src/lilypondcairo-2.19.21/lily/simple-spacer.cc,cine251
_expression_
(Configuration_length(cur_force)_cur_len) (less than sign--not on my keyboard) le-6
that's Greek to me, but maybe will be helpful for you, Jeremiah.
I've attached the denemo file.
