(Get the code!)
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:

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.
