Thank you, Colin, for CC-ing me.

The output of all 2.15.x version was verified by repeating the test
yesterday and running it today again. These are not some random
errors.
These tests were performed on my desktop computer
(http://wiki.przemoc.net/about/my_hardware) with Debian Wheezy 64-bit
using 64-bit version of LilyPond.

Today I tested:
- 64-bit LilyPond 2.15.30, work notebook (Dell Vostro 3750), Wheezy
x64 - segfault
- 32-bit LilyPond 2.15.30, desktop, Wheezy x64 - ok
- 32-bit LilyPond 2.15.27, desktop, Windows XP x64 - ok

I'm sorry, because maybe I mixed things and possibly never run it on
Windows before. Damn.
Thus it looks like a 64-bit only problem. Not sure whether it's Linux
specific (Don't have FreeBSD).

Regards.

P.S. BTW Installation/extraction script could be improved (e.g. it
optimistically assumes that default shell is a full blown one,
supporting -s and -n in read invocations), so I could not extract it
in the first run. I'll hopefully send a fixed version next weekend.
