boost/math_fwd.hpp is now working for me, thanks a lot! However I maybe found another regression introduced after the 1.64 release, this time in Boost.Thread (with pthread implementation and BOOST_HAS_NANOSLEEP). A minimal example: #include int main() { boost::this_thread::sleep(boost::posix_time::seconds(1)); } This sleeps "forever", however a slightly more complicated program might not. I bisected it to this commit: https://github.com/boostorg/thread/commit/d4cff01c724f1355fef0990f3d6d678e52... The problem seems to be the BOOST_THREAD_USEFIXES_TIMESPEC define, which alters some internal behavior, effectively changing

nanosleep({0, 999366710}, NULL)

into

nanosleep({1501988898, 350057596}, [stuck for a very long time]

. If the sleep is called inside a boost::thread, hidden::sleep_until is implemented via condition.do_wait_until instead of nanosleep, this works. For me a slightly extended test code works as expected if compiled in debug mode but is stuck in release mode. I'm testing under Linux with GCC 7.1 and a Clang++ 5.0.0 snapshot.
