The same happens for page-markers (i.e., \break, \pageBreak, \label, etc.):
mypart = \bookpart {
\label #'foo
}
% also crashes
\bookpart { \mypart }
It seems that when a book is cloned, the copy constructor assumes all
elements in the original book to be scores, which is unsafe: the
elements can also be markup or page-markers:
#(display (ly:score? (car (ly:book-scores mypart))))
-> #f
Cheers,
