Symbol's function definition is void: #:--post-body--27977

[Michael Heerdegen <michael_heerdegen@xxxxxx>]

Dear Bug Team!

in an emacs -Q from an up-to-date developer Emacs 24, load w3m, do M-x
w3m, hit g, enter an URL and hit RET.  You'll always get the following
error:

error in process sentinel: w3m-process-sentinel: Symbol's function
definition is void: #:--post-body--27977


Background:

This bug is related to a recent change of the behavior of the `labels'
macro in the CL package.

With former versions of the CL package, something like the following
worked:

  (labels ((fak (n) (if (< n 2) 1 (* n (apply 'fak (list (1- n)))))))
    (fak 5))

meaning you could call `apply' on the quoted (with "'") symbol of a
labels definition, like "'fac" in my example.

This has now been considered a bug by emacs dev.  You _must_ quote
the symbol with #' now, like this:

  (labels ((fak (n) (if (< n 2) 1 (* n (apply #'fak (list (1- n)))))))
    (fak 5))

The first variant with the simple "'" quote doesn't work anymore,
evaluating it will give you an error.

To fix the bug described here above, please modify
`w3m-process-do-with-temp-buffer' in "w3m-proc.el" so that it respects
this rule.  This fixes the bug for me.

Please also check if other occurrences of `labels' in the code must be
modified as well.


Best regards,

Michael.
