I tried again with the version of gcc from the 4.3 release branch (Subversion
branch gcc-4_3-branch downloaded today) and can still reproduce the bug (and
also can still reproduce the successes with no optimization or with
-fno-automatic -O2 but not -funroll-loops).

This is on an up-to-date Debian Sid system.  (N.B. are you aware that Debian
3.1 is no longer security-supported?)
