crash while processing lily-7d242e8d.ly

[Werner LEMBERG]

[git from today]

Running

  lilypond lily-7d242e8d.ly

makes lilypond crash.  Below is the full backtrace (I configured with
--disable-optimisation, BTW); not very informative, but...

valgrind gives the following:

 Invalid read of size 4

  Address 0x404 is not stack'd, malloc'd or (recently) free'd

Interestingly,

  lilypond -dbackend=eps lily-7d242e8d.ly

works just fine.
