Corrected TIR would not cause the problem, please defined the write buffer
for root block as follows:
```
@tvm.script.ir_module
class Module:
@T.prim_func
def bad_message(
B: T.Buffer[(64), "float32"],
B_pack: T.Buffer[(8, 8), "float32"],
):
with T.block("root"):
T.reads()
T.writes()
for jo in range(8):
for ji in range(8):
with T.block():
vo, vi = T.axis.remap("SS", [jo, ji])
B_pack[vo, vi] = B[vo * 8 + vi]
```
And still the problem lies in bad message for error reporting, would work on
that later.
