11672	Thread: Should use unique_ptr, not auto_ptr	Ben Wiederhake <Ben.Wiederhake@…>	viboes	"Boost.Thread has two occurrences of `auto_ptr`, which is deprecated since C++11:

{{{
$ grep -rn 'auto_ptr'
include/boost/thread/detail/thread_group.hpp:78:
  std::auto_ptr<thread> new_thread(new thread(threadfunc));
src/win32/thread.cpp:156:
  std::auto_ptr< ThreadProxyData> data(reinterpret_cast< ThreadProxyData*>(args));
}}}

This causes a warning when compiling with gcc-5.2, and soon other compilers as they become compliant with the clause ""std::auto_ptr is deprecated"".

I can see the following ways to resolve the warning:

- Literally silence the warning, like in #11622. I view this as a very bad idea.
- Use `std::unique_ptr` if using C++11 or newer. I view this as a bad idea.
- Use `boost::movelib::unique_ptr`. I view this as a good idea.

I checked both occurrences of `auto_ptr` by hand, and found that in both cases, std::unique_ptr can be used just as well! (In both cases, `auto_ptr` is only used to guarantee a call to `delete` in case anything throws.)"	Bugs	closed	Boost 1.60.0	thread	Boost 1.59.0	Problem	fixed	auto_ptr
