Your error isn't caused by shared_ptr, but by ASIO's "fenced block" in 
boost/asio/detail/fenced_block.hpp and 
boost/asio/detail/gcc_sync_fenced_block.hpp. I've no idea what this "fenced 
block" is supposed to do - it seems to insert or try to insert memory 
barriers - but on M68K, it should be safe to disable it via 
BOOST_ASIO_DISABLE_FENCED_BLOCK.
