That function is

$ c++filt 
_ZN5boost6detail12set_tss_dataEPKvNS_10shared_ptrINS0_20tss_cleanup_functionEEEPvb
boost::detail::set_tss_data(void const*, 
boost::shared_ptr<boost::detail::tss_cleanup_function>, void*, bool)

which as far as I know, belongs to the Boost threads library. You might
have to link against it.
