Debian's maintainer committed a fix, but apparently it's broken on certain  
architectures?

I'm really suspicious, since their current fix seems correct.  Here is  
their solution:

         (do-measurements (ly:get-option 'dump-profile))
         (handler (lambda (key failed-file)
                    (set! failed (append (list failed-file) failed)))))
