Same result on PowerPC with gcc 4.6.1:
/usr/lib/gcc/powerpc-lynx-lynxos/4.6.1/../../../../powerpc-lynx-lynxos/include/boost/lexical_cast.hpp:
In instantiation of 'bool boost::detail::lexical_stream_limited_src<CharT,
Base, Traits>::operator<<(long double) [with CharT = char, Base =

This only appears with -O2 -flto and passes -Os -flto.

gcc -v:
Using built-in specs.
