Thank you Stefan and Alan in another email.
With the hint, I find out the `async-bytecomp-package-mode` is turn on
by the package `helm-core`. So it is a bug of `async-bytecomp` maybe,
and I will report it the package author.
Sorry for the misleading information in the orignial email.

IIUC the above error involves some part of the `async` package.
Could you give a bit more information about how you hooked `async` with
`package`?
