From: "paolo.carlini at oracle dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/57920] [c++11] Linux: std::random_device reads too much from /dev/urandom Date: Sun, 21 Jul 2013 20:40:00 -0000 [thread overview] Message-ID: <bug-57920-4-w4TVqvdv34@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-57920-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57920 Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |ASSIGNED Last reconfirmed| |2013-07-21 Assignee|unassigned at gcc dot gnu.org |paolo.carlini at oracle dot com Ever confirmed|0 |1 --- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> --- I'm going to attach a patchlet which does the trick (fread -> read) for me. Note I'm on purpose disabling the use of __builtin_ia32_rdrand32_step on my x86_64 machine, the undef would not be in the committed patch of course. It would be great if you could test the change on your machines (in 4.7.x just change random.h, no need to rebuild) and confirm that everything is fine.
