boost::move from lvalue does not work with gcc

[anonymous]

boost::thread make_thread1() {

boost::thread x=make_thread(); return boost::move(x);

}

Compilation of the function above produces the following error with gcc-3.4.4 and 4.3.2:

gcc.compile.c++ ../../../bin.v2/libs/thread/test/test_thread_move.test/gcc-3.4.4 /debug/threading-multi/test_thread_move.o test_thread_move.cpp: In function `boost::thread make_thread1()': test_thread_move.cpp:31: error: no matching function for call to `boost::thread: :thread(boost::thread)' ../../../boost/thread/detail/thread.hpp:200: note: candidates are: boost::thread ::thread(boost::detail::thread_move_t<boost::thread>) ../../../boost/thread/detail/thread.hpp:108: note: boost::thread::thread(boost: :thread&) test_thread_move.cpp:31: error: initializing temporary from result of `boost:: thread::thread(boost::detail::thread_move_t<boost::thread>)'

It seems that this ticket should be reopened.

The is an action point to use Boost.Move. Could we consider this as a duplicate of #6194 Adapt to Boost.Move.

[viboes]

This test pass on trunk now.
