confirmed
for O1 :
Apparently, we have concluded that the indirect references are not required
when there is a 0 offset for the var. When the offset is non-zero (v.b, v.c,
v.d), we correctly construct the indirect ref.
for O0, all the references are correctly formed (and there is a corresponding
L_w$non_lazy_ptr).
