Tested gcc 4.2.1, generates identical code:
000000aa T find_pair
000000aa T find_pairB
000000aa T find_pairC
000000aa T find_pair
000000aa T find_pairB
000000aa T find_pairC
Also did a diff of .s files:
# diff -u vi_small.s vi_big.s
--- vi_small.s Sun Jul 22 00:38:33 2007

At least this testcase passes now. Maybe this is fixed in 4.2 indeed. Thanks!
