The problem is associated with the message "no solution found for Bezier 
intersection"
in bezier.cc, which seems it would return 0.0 to slur_outside_callback. It is 
easy
to believe that would misplace the fingering that is trying to avoid the slur.

bezier.cc hasn't changed since 2.15.12

Probably a difference in evaluation between Linux and Windows builds.  Floating 
point
evaluation can vary a little, but we should be able to make those variations 
not matter.
The only suspicious-looking thing I see is the use of only the first and last 
solutions
returned by the polynomial root-finder.
