That would be welcome. I looked through the function right now and saw
no obvious problematic candidate.
simultanous-music-iterator.cc is short enough to look through the
generated code manually. If you compile it (of course with all other
relevant options) and options -S (for generating assembly source) and
-fverbose-asm then I should have a reasonable chance of finding problems
in the generated code by manual inspection.
This is sort of curious since the actual error message is generated in
timing-translator.cc, after looking at the current and the previous
moment in the global context.
On the other hand, the output makes it likely that the shorter note
advances time too much for some reasons.
