Follow-up Comment #1:

Thanks for the report.

Confirmed on 4.1.0+ & 3.9.0+

After stepping through the code I think the culprit is the call (at L.147) to
canonicalize_file_name. That function converts native Windows backslash
fileseps into forward slashes.

A similar alternative function (make_absolute_filename) leaves the file
separators intact; but it has to be tested on Linux as well before that change
can be made safely; as there seem to be some subtle differences between
canonicalize_file_name and make_absolute_filename.  I had earlier discussion
on this subject some years ago as regards drive letters on Windows (I see no
unpack tests for that BTW), see here: https://savannah.gnu.org/bugs/?36677

Even then the test (first assert in unwind_protect block) fails for me:

>>   assert (filelist{1}, filename);

error: ASSERT errors for:  assert (filelist {1},filename)

  Location  |  Observed  |  Expected  |  Reason

      C:\Users\philip\AppData\Local\Temp\oct-32                 Strings don't
match
