Comment:

 Fixed in git develop and master, will be released in 1.56.

 The default constructor of atomic_flag cannot be trivial in C++03 because
 the copy constructor has to be declared private (to prohibit copying).
 With a C++11 compiler the implementation now defines a constexpr
 constructor which basically provides the same guarantees as the trivial
 constructor would have. Also, BOOST_ATOMIC_FLAG_INIT is provided in this
 case.
