The same error occurs while compiling the Debian package autodocksuite from sid
with LTO enabled:

g++ (Debian 20110816-1) 4.7.0 20110816 (experimental) [trunk revision 177785]

Sorry for not isolating the problem more. The problem could not be observed in
g++ 4.6.1 from Debian unstable (4.6.1-8). It fails later, hence the
installation of the snapshot :) Without the LTO, everything is fine.
