I've observed this instability with multiple voices newly created in 
lots of bars, but never been able to tie it down to anything other than 
"complexity", even in a single page of piano music. Sometimes changing a 
single note can bring it on; sometimes adding another bar (with yet more 
voices!) makes it work again. I conjecture that creating new voices in 
every bar puts a strain on the memory management which it is not up to.

I have changed to the style of having just a few multiple voices which 
run for the length of the piece, only adding local voices occasionally 
when called for. Writing like this the problem doesn't appear.
