I can crash 2.2.1 on Debian Woody!

[Steve Shorter]

Howdy!

        I have a smallish .ly file that will crash lilypond 2.2.1 on Debian 
Woody.
Is this a bug or is there somthing wrong with the source file. It parses
without any other errors or warinings.


        lilypond crashes with this output
