--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-03-31 12:40:24 UTC --- Thanks for the fix, Jason, I've just encountered the bug myself using boost::thread I expect others will to, so for the benefit of search engines, the error is post_event_test.cc:130:47: error: cannot bind 'void()' lvalue to 'void (&&)()' /home/jwakely/src/boost/boost_1_45_0/boost/thread/detail/thread.hpp:167:9: error: initializing argument 1 of 'boost::thread::thread(F&&) [with F = void()]'
