I think it is unlikely that this is an issue in apache2. Probably it's a problem in ltrace. You could try latrace instead, which does basically the same. I cannot reproduce this here (on unstable, or in a jessie/stable chroot on a 4.6 kernel from unstable). If you think this is important, you could try to get more detailed info, as described in /usr/share/doc/apache2/ README.backtrace . Cheers, Stefan
