Comment #1 on issue 3205 by [email protected]: opening bar check causes crash if
\score contains the \midi block

Issue 3205: opening bar check causes crash if \score contains the \midi
block
This derives Bar_check_iterator from Music_iterator rather than from
Simple_music_iterator.
In
\score {
{ | d }
\midi { }
}
the bar check iterator is being called while only the \Global context
exists. That causes Score_performer::one_time_step to be called
without getting Score_performer::prepare to be called previously,
probably because the Score context is created at the wrong time. The
Score_performer is not prepared for this situation.
I have no idea how to fix Simple_music_iterator, why it exists in the
first place and is written like it is, and why this appears to work.
