https://svn.boost.org/trac10/ticket/7012 <p> The relevant code: #if defined(EPOLL_CLOEXEC) </p> <blockquote> <p> int fd = epoll_create1(EPOLL_CLOEXEC); </p> </blockquote> <p> #else <em> defined(EPOLL_CLOEXEC) </em></p> <blockquote> <p> int fd = -1; errno = EINVAL; </p> </blockquote> <p> #endif <em> defined(EPOLL_CLOEXEC) </em></p> <blockquote> <p> if (fd == -1 &amp;&amp; errno == EINVAL) { </p> <blockquote> <p> fd = epoll_create(epoll_size); </p> </blockquote> </blockquote> <p> .... </p> <p> with glibc 2.13 EPOLL_CLOEXEC is always defined but epoll_create1 may return ENOSYS which causes the code below to fall though.
