Thanks for your answer.

Could you give me a few pointers as to how I would find those size? I would then be more than happy to do a thorough investigation.

clang++ -Os and -O3 gives nearly the same size for the .o file here. The problem appears when clang++ links that .o to make the .so
It's is linking against a dylib Boost.Python library by the by. But I may be missing your point completely here.
