It has to do with garbage collection, which is triggered at
unpredictable times. I introduced something over the weekend that I
probably shouldn't have done: I converted music-iterators to Scheme
objects, in the hope of producing a \property \once soon.

Of course, it all works over here (GUILE 1.7 CVS).

You could help track this down, by running the lilypond command line
through valgrind (http://developer.kde.org/~sewardj/), i.e.


valgrind --num-callers=10 --suppressions=guile.supp lily/out/lilypond
  lily-XXXX lily-XXXX lily-XXXX lily-XXXX lily-XXXX lily-XXXX
  lily-XXXX

and adapting the guile.supp from the following (GUILE 1.7) suppression
file:

In the meantime, I'm checking if compiling -O2 will trigger any
bugs...

# guile valgrind suppression file

    guilegc
        Value4

    guilegc
