Quicklisp error in Lispworks

Question

I'm running LispWorks 7.1 on OSX (macOS High Sierra). I sometimes encounter a Quicklisp loading bug (I say sometimes because when I restart LispWorks I sometimes don't see this error again).

Example:

CL-USER 1 > (ql:quickload "iterate")
To load "iterate":
  Load 1 ASDF system:
    asdf
  Install 1 Quicklisp release:
    iterate

Error: Error detected during deflate decompression: Corrupted Data detected during decompression: Incorrect huffman code (1E55) in huffman decode!
  1 (abort) Give up on "iterate"
  2 Return to top loop level 0.

Type :b for backtrace or :c <option number> to proceed.
Type :bug-form "<subject>" for a bug report template or :? for other options.

Any idea what's going on?

I've verified I have a recent client:

CL-USER 6 > (ql:update-client)
The most up-to-date client, version 2017-03-06, is already installed.
T

Also, the backtrace, in case it helps:

CL-USER 12 : 1 > :b

As Rainer Joswig pointed out, I just had to (duh!) apply the latest patches.

For future reference, this involves

Downloading the patches listed here
Copying them to the appropriate private-patches directory (e.g. /Applications/LispWorks\ 7.1\ \(64-bit\)/Library/lib/7-1-0-0/private-patches for me)
Modifying load.lisp in the directory accordingly (in this case, adding (load-one-private-patch "lisp-memory-copy-32-chunks" :system64) and (load-one-private-patch "replace-i-vectors" :system))
Restarting Lispworks
