This bug is probably caused by bug #62582 but I am not sure, because HTTP functionality is badly broken in MIT Scheme 11.2.

(let* ((socket (open-tcp-server-socket 8000))
       (port (tcp-server-connection-accept socket #t #f))
       (request (read-http-request port)))
  (display request))

When I run the code above and access localhost:8000 using a web browser, the `read-http-request` procedure will fail with:

;The object #[textual-i/o-port 12 for channel: #[channel 13]], passed as an argument to #[compiled-procedure 14 ("binary-port" #x2) #x1c #x1a7a6f4], is not the correct type.

So, I changed `tcp-server-connection-accept` to `tcp-server-binary-connection-accept`:

(let* ((socket (open-tcp-server-socket 8000))
       (port (tcp-server-binary-connection-accept socket #t #f))
       (request (read-http-request port)))
  (display request))

However, this will also fail when a client connects to localhost:8000:

;The object 3, passed as the second argument to vector-ref, is not in the correct range.

MIT Scheme version: 11.2
