Remhash of pathname sometimes fails

Bug Description

sbcl 1.3.18 on windows x64 only (have not tested 32-bit x86 windows)
put this in any file and load it:

(let* ((map (make-hash-table :test 'equalp))
       (key #P"some/path/"))
  (setf (gethash key map) "my-value")
  (format t "Printing: ~A~%" key)
  (print (remhash key map))
  (print (hash-table-count map)))

Output is surprisingly:

Printing: some/path/


Removing the format statement causes the remhash to succeed.

Oh, I confirmed that this reproduces under wine, so no need to fire up a real windows box to look at it.

And pillton reports that it reproduces on OSX 10.10.5, so this may not be windows specific.

I can reproduce it on Linux with 1.3.20

It does not reproduce on Linux with 1.3.17 which narrows it down to between 1.3.17 and 1.3.18; this places suspicion on though I haven't bisected yet
