libstdc++: Fix for explicit copy ctors in <thread> and <future> [PR106695]
When I changed std::thread and std::async to avoid unnecessary move
construction of temporaries, I introduced a regression where types with
an explicit copy constructor could not be passed to std::thread or
std::async. The fix is to add a constructor instead of using aggregate
initialization of an unnamed temporary.
libstdc++-v3/ChangeLog:
PR libstdc++/106695
* include/bits/std_thread.h (thread::_State_impl): Forward
individual arguments to _Invoker constructor.
(thread::_Invoker): Add constructor. Delete copies.
* include/std/future (__future_base::_Deferred_state): Forward
individual arguments to _Invoker constructor.
(__future_base::_Async_state_impl): Likewise.
* testsuite/30_threads/async/106695.cc: New test.
* testsuite/30_threads/thread/106695.cc: New test.
