AMD CPU Bug Discovered?

While there isn't a whole lot of info here just yet, it would seem that an independent researcher has discovered a bug in AMD processors. This is what AMD had to say about the discovery:

AMD has taken your example and also analyzed the segmentation fault and the fill_sons_in_loop code. We confirm that you have found an erratum with som e AMD processor families. The specific compiled version of the fill_sons_in_loop code, through a very specific sequence of consecutive back-to-back pops and (near) return instructions, can create a condition where the process or incorrectly updates the stack pointer.
