Nope.

On closer inspection, it is the call to (cgi:upload ...) which throws
the error so there is no way of converting the result to a vector before
trying to write it to disk.

 cgi.scm:

 (define (upload name)
   (and=> (uploads name) car))

cgi.scm is so full of closures it makes my head swim but from what I can
gather the upload is extracted and stored in memory at the
initialisation stage (cgi:init) which would suggest to me that the
problem doesn't lie within the procedure parse-form-multipart as this is
called by (cgi:init).

Given that guile 1.8.6 can actually handle null chars in strings
(despite what the error message says) what could the problem be?

P.S. Documentation bug - the procedure 'and=>' is missing from the
     manual.  What's the difference between the way the upload procedure
     is written above and simply:

      (define (upload name)
        (car (uploads name)))
