When I was writing the trill code, lily tended to crash when trying to
compress music so that the trill took the same length as the original
note. I worked around it by fixing a trill's note length as a
demisemiquaver in the current tempo.
You can try:
#(define ac:maxTwiddleTime (ly:make-moment 1/120))
#(define (ac:twiddletime music)
(let* ((tr (filter (lambda (x)
(and (eq? 'ArticulationEvent (ly:music-property x 'name))
(string= "trill" (ly:music-property x
'articulation-type))))
(ly:music-property music 'elements)))
(ac:targetTwiddleTime ac:maxTwiddleTime)
(pre-t (if (pair? tr) (ly:music-property (car tr) 'twiddle)
'()))
(hemisemimom ac:targetTwiddleTime))
(if (ly:moment? pre-t)
pre-t
hemisemimom)))
but you may find durations incorrect.
