spy-on test fails with native-compilation

I believe this is #230 again. When building with Guix and using native compilation, the tests fail for spy-on. Here is the relevant part of the output:

The Spy
  `spy-on' function
    replaces a symbol's function slot (0.05ms)
    restores the old value after a spec run (0.05ms)
    allows a spied-on command to be executed as a command (0.09ms)
    can spy on autoloaded functions (0.82ms)
    can spy on non-existing functions (0.03ms)
    only accepts ARG for keywords that use it (0.16ms)
    works on native-compilation primitives  Expected `(spy-on 'buffer-file-name)' not to throw a child signal of `error', but it threw (native-lisp-load-failed "file does not exists" "/homeless-shelter/.emacs.d/eln-cache/28.2-bf9ead57/subr--trampoline-6275666665722d66696c652d6e616d65_buffer_file_name_0.eln") (142.85ms)
    will signal en error if
      used in before-all (0.08ms)
      used directly in describe (0.06ms)
  :to-have-been-called matcher
    returns false if the spy was not called (0.08ms)
    returns true if the spy was called at all (0.07ms)
  :to-have-been-called-with matcher
    returns false if the spy was not called at all (0.10ms)
    returns false if the spy was called with different arguments (0.10ms)
    returns true if the spy was called with those arguments (0.18ms)
  :to-have-been-called-times matcher
    returns error if the spy was called less than expected (0.10ms)
    returns error if the spy was called more than expected (0.09ms)
    returns true if the spy was called the expected number of times (0.08ms)
    use plural words in error message (0.09ms)
    use singular expected word in error message (0.11ms)
    use singular actual word in error message (0.09ms)
  :and-call-through keyword functionality
    tracks calls to the function (0.04ms)
    passes the arguments to the original function (0.07ms)
  :and-return-value keyword functionality
    tracks calls to the function (0.03ms)
    returns the specified value (0.07ms)
    works with strings (0.07ms)
    works with vectors (0.07ms)
    works with symbols (0.07ms)
    works with conses (0.07ms)
    works with lists (11.05ms)
    works with alists (0.06ms)
  :and-call-fake keyword functionality
    tracks calls to the function (0.02ms)
    returns the specified value (0.05ms)
  :and-throw-error keyword functionality
    throws an error when called (0.06ms)
  error-recording functionality
    records the function as called even if it throws an error (0.09ms)
    counts both successful calls and calls that threw errors (0.09ms)
    records args to the function whether it throw an error or not (0.12ms)
    records the signal thrown by a call to the function (0.12ms)

and backtrace of the guix build:

This is for v1.30, not sure what is wrong since this was supposed to be fixed. Note that the homeless-shelter is noting that HOME is not set during the build/test (though I did try setting it to /tmp in the package build, perhaps a red herring here as it normally indicates something is relying on HOME).

Could be a Guix related issue with how the build is done, but I don't see what that is so far...
