It's not obvious, but this page should help:

Your code does naughty things inside a callback.

I should have seen the problem myself :( 

 LilyPond turns a
blind eye to such things unless you're compiling with optimising
disabled.

I don't know anything about optimising.
Searching the archives, it seems that optimising is enabled in every released version.
IIUC, it could be disabled for compiling LilyPond from master.
How to do, i.e what should I type?
I found no hint in our manuals.

alwaysPrintWholeLaThinBassDrum =

\override NoteHead #'duration-log =
  #(lambda (grob)
     (let* ((style (ly:grob-property grob 'style))
            (grob-probs (ly:grob-properties grob))
            (cause (assoc-get 'cause grob-probs))
            (drum-type (ly:prob-property cause 'drum-type)))

     ;; If laThin-NoteHead for bassdrum is detected,
     ;; change duration-log, else default.
     (if (and (eq? style 'laThin) (eq? drum-type 'bassdrum))
         (ly:grob-set-property! grob 'duration-log 0)

This should just be `0'.

 

Yep.

 

Cheers,
Neil

Thanks,
