Hi,

the code below returns
programming error: no solution found for Bezier intersection
for 2.19.82 as well as for current master. 2.18.2 is ok.

\new Voice \with { fingeringOrientations = #'(left) }
  \oneUp

It's a heavily boiled down version of the original file (thus the
strange octaves).
Though I'm not able to boil it down even more.

The error-message is obviously created in bezier.cc, no clue what's the problem.
