Problem with MIDI generation with 2.1.18

[darius]

Hi !

I upgraded to cygwin 2.1.18 yesterday, and experienced two problems:

-  \autochange does not seem to work as well as it used to be.
    I guess I did something wrong. Here is my PianoStaff:

solo = \context PianoStaff = solo <<
        \property Staff.midiInstrument="vibraphone"
        \context Staff=up { 
           \property Staff.midiInstrument="vibraphone"
            \context Voice=foo{
               \notes { \time 4/4  \key b \minor }
                \voiceOne
                \HighSoloNotes
            }
        }
        \context Staff=down {
            \property Staff.midiInstrument="vibraphone"
             \notes { \time 4/4  \key b \minor }
            \clef bass
            \autochange \context Voice = bar {\LowSoloNotes}
        }
    >>



- MIDI file generation crashes with a stack trace (the log is given below)
  I tried to simplify a number of things, assuming that this might be due
  to excessively complex data structure, but it did not help. 

  This raises a related question about Lilypond's internals: 
  when are variables expanded ? when I write:

a = \notes {a b c d e f }

b = \notes { \a \a \a }

  are the a's in b expanded when declaring b, or when actually using b ?

Cheers,

Darius/.
