As far as I can tell, the bug could affect *all* architectures, since
the bug is an overly-aggressive optimization in the arch-independent
part (the buggy function is maybe_eliminate_biv_1() in loop.c).
There have been posted code that exhibits the bug on the kernel list
yesterday. I have it at home, but I'm headed straight for my family
in Copenhagen (I'm in Aarhus) after work, so I wont have time to send
it out before I come back in january.
Actually, a possible fix (by switching off the buggy code in gcc) was
posted on gnu.gcc.bug already in *September*. However, it did not
make it into 2.7.1 or 2.7.2 -- I might note that the bugfix was sent from
Germany, and it *appears* that FSF is rather slow to put in code / bug
fixes that comes from Europe :-/
