This is caused by an optimization introduced in glibc that causes memcpy() to copy in reverse. This breaks code that used memcpy() for overlapping copies in violation of ANSI C. There is a bug at the Fedora bug tracker documenting this where Linus Torvalds posted his two cents:
https://bugzilla.redhat.com/show_bug.cgi?id=638477 Anyway, the fix is to apply the patch at the libsdl bug tracker to libsdl. While the fix is trivial, it would be problematic if a major Linux distribution shipped a release with this bug in it. I suggest that this be made a blocker to Ubuntu 11.04's release to ensure that this is addressed before Ubuntu 11.04 ships next month. Also, would the package maintainer take the initiative to notify his Debian counterpart? I am the Gentoo Linux user that filed the Gentoo bug about this and I don't plan to notify many more people. The only reason I cared about this bug on Ubuntu to talk about it here is because it affects someone I know. ** Bug watch added: Red Hat Bugzilla #638477 https://bugzilla.redhat.com/show_bug.cgi?id=638477 -- You received this bug notification because you are a member of Debian/Ubuntu Games Team, which is subscribed to wesnoth-1.8 in ubuntu. https://bugs.launchpad.net/bugs/725044 Title: SDL rendering issue: graphic corruption while scrolling right Status in “libsdl1.2” package in Ubuntu: New Status in “wesnoth-1.8” package in Ubuntu: Invalid Status in Fedora: Unknown Status in Gentoo Linux: Unknown Bug description: Binary package hint: wesnoth-1.8 using natty 11.04 with latest updates as of today (25.2) when playing and scrolling to the right the screen gets corrupted, scrolling up/down/left works as expected there is also a screenshot + a small diff available in the wesnoth forums -> http://forums.wesnoth.org/viewtopic.php?uid=109471&f=4&t=32423&start=0 it happens using nouveau and nvidia binary driver.. _______________________________________________ Pkg-games-ubuntu mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/pkg-games-ubuntu
