To fix it we need to explicitly call default constructor of `noncopyable` in constructors of `progress_display` and `progress_timer`. Example: {{{ explicit progress_timer( std::ostream & os = std::cout ) // os is hint; implementation may ignore, particularly in embedded systems : timer(), noncopyable(), m_os(os) {} }}}" Patches closed Boost 1.55.0 timer Boost 1.54.0 Problem fixed
