Hi, Sorry for being unclear; there recently was an optimization in libc6's memcpy (on amd64) that broke some programs because they assumed memcpy behaved like memmove. Please have a look at [1], which lists the libraries and how to use them (on jh_manifest). If you are not on an amd64 / 64bit user space or if the preloading does not work, let me know because that implies it not an issue with (misusing) libc6's memcpy. ~Niels [1] /usr/share/doc/libc6/NEWS.Debian.gz See entry 2.13-7 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
