Previously users of the function guarded against this but that was removed as part of the zeroing elimination.

SUGGESTED FIX http://analemma.sfbay.sun.com/net/prt-archiver.sfbay/data/archived_workspaces/main/c2_baseline/2005/20051201180148.never.c1/workspace/webrevs/webrev-2005.12.01/index.html

EVALUATION This is correct. The fix is to added a test for zero to the unaligned case. All other cases are correct.
