compilation error on g++ (Debian 4.8.2-16) 4.8.2 or g++ (Debian 4.9-20140303-1) 4.9.0 20140304 (experimental) [trunk revision 208299]

[hg42]

compiling with g++ 4.8.2-16 fails (see log below).
Exactly the same output for g++ 4.9-20140303-1.
Using 4.7 works (for this I had to downgrade g++ and g++-multilib to 4.7).

Operating system: [linux2]
