Hello,

when updating packages with M-x package-list-packages, and using
async-bytecomp.el to compile, some users get an error like this one:

error in process sentinel: async-when-done: Invalid read syntax: "#<"
error in process sentinel: Invalid read syntax: "#<"

This seems to be related to the recent addition of symbols with
positions.

async uses `async-inject-variables' to collect variable bindings of
interest and deliver them to the other Emacs instance.  The return value
contains symbols with positions in some scenarios.

The root of the trouble seems to be the value of
`byte-optimize--dynamic-vars'.  As soon as I byte compile any file, I
see lots of symbols with positions in `byte-optimize--dynamic-vars'.

Is that expected?  What has to be done?

TIA,

Michael.
