Note that the second example in the file produces a segfault for

my fault.
While I can't say for certain, but this is probably because
StaffGroup already has Span_bar_engraver, and your code attempts to
add an engraver to a context that already has that engraver.
Incidentally, I see the behavior with the lyrics, and before I add
it, I just wanted to see if I could get different results.
