I managed to hit this myself.  I'm not exactly sure what triggered it.
My problematic fix-list looks like this:

    (#s(uniquify-item :base "term-tests.el" :dirname 
"/home/npostavs/src/emacs/master/test/lisp" :buffer #<buffer term-tests.el> 
:proposed nil)
    #3=#s(uniquify-item :base #1="term-tests.el" :dirname 
"/home/npostavs/src/emacs/emacs-master/test/lisp" :buffer #<buffer 
emacs-master/term-tests.el> :proposed #1#)
    #4=#s(uniquify-item :base #2="term-tests.el" :dirname 
"/home/npostavs/src/emacs/emacs-26/test/lisp" :buffer #<buffer 
emacs-26/term-tests.el> :proposed #2#)
    #3# #4#)

I suspect the problem is happening earlier, so we'll need some other
test to catch it.
