the attached preprocessed source does not compile with g++-4.2. it does compile
with g++-4.0, 4.1 and 4.3, though, so i don't know whether there is any
interest to work on a reduced test case and work on a bug fix ...
from my reading of the compiler error, it has to do with the compiler-generated
copy constructor ...
