Segfault with multimeasure rests and metronome markings

[Chris Snyder]

We've run into a segfault in all versions of LilyPond after 2.13.32, 
including 2.13.44. I've narrowed it down to occur when a tempo marking 
is placed over a multimeasure rest when the Metronome_mark_engraver has 
been added to the staff containing the rest:

----

\version "2.13.44"
% works in 2.13.32 and prior

\score {
        \new Staff {
                \tempo 4=150
                R1 |
        }
        \layout {
                \context {
                        \Score
                        \remove "Metronome_mark_engraver"
                        \remove "Staff_collecting_engraver"
                }
                \context {
                        \Staff
                        \consists "Metronome_mark_engraver"
                        \consists "Staff_collecting_engraver"
                }
        }
}

Console output:

Processing `RestSegfault.ly'
Parsing...

Preprocessing graphical objects.../home/csnyder/bin/ly-choose: line 29: 
 7328 Segmentation fault      $ly $*
LilyPond [RestSegfault.ly] exited with return code 139.

(ly-choose is my own wrapper script to run the version of LilyPond 
specified in the \version parameter; the segfault still occurs when this 
script is not used)

I'm running Kubuntu 10.10 64-bit using the official LilyPond binaries.

Thanks,
Chris
