--- Comment #5 from qinzhao at gcc dot gnu.org ---
the following code in gimple-fold.cc has issue:
4440 tree dst = build2_loc (buf->loc, MEM_REF, atype, buf->base,
4441 build_int_cst (buf->alias_type,
4442 buf->off + end
4443 - padding_bytes));
this is the place that generate the wrong:
MEM <char[4]> [(struct outer *)&o + 4B] = {};
as I checked, buf->off is 0, padding_bytes is 4, both are correct. but the
value of "end" is 8, which is not correct for the structure "outer", it should
be 72.
