The test fails at sample/test.rb:1848, which is

ary2 = $x.unpack($format)

We had a gcc-4.6 bug (http://bugs.debian.org/635126) which manifested 
itself as a miscompilation of pack/unpack function in Ruby. The bug 
got fixed in gcc-4.6 4.6.2-6 and the latest build attempt was done 
with 4.6.2-4, so it did not contain this fix. I'd say giving it back 
is pretty pointless unless we can bump gcc-4.6 version to 4.6.2-6 or 
later (which is a very good idea anyway, because we currently build 
packages with known bad compiler version).
