--- Comment #18 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
If the control flow goes through .L12:

.L12:
        b .L3    ; return 0; (not interesting, fall through)
        ldi 1,%r28

the return value will be 1 since ldi is in the delay slot of the branch.

What happens if you compile with -O2 -fno-delayed-branch instead?=
