I just built the 2013.56 release and am receiving segfaults on startup. The offending line is the fwrite() in random.c in write_urandom().
Our RHEL 5 servers appear to have /dev/urandom as read-only. I am guessing that is likely the root cause. Commenting out the internals of write_urandom() stopped the segfault. Maybe a build flag to avoid writing to /dev/urandom would be appropriate for some platforms? Thanks, Scott
