There might be some interaction with BOOST_LOG_USE_COMPILER_TLS from the 
sounds of it. Try disabling/enabling that and see if that narrows it 
down further.

It does look like you're doing the right thing, but ensure that your 
shared object will invoke global C++ constructors. I remember some *nix 
somewhere at some time that didn't do this.
