13490	Compile error when BOOST_FIBERS_NO_ATOMICS is open	tdzl2003 <tdzl2003@…>	olli	"It's actually a bug about Boost::fiber but I can't find that component on bug page.

include/boost/fiber/context.hpp: ln 392:

ctx->use_count_.fetch_add( 1, std::memory_order_relaxed);

While BOOST_FIBERS_NO_ATOMICS was defined, type of ctx->use_count_ is std::size_t, which is not a object and doesn't have fetch_add method, so this line failed to compile. There are also other compile errors, like remote_ready_hook_ is not defined but used at scheduler.hpp.

full compile error is:
