Of course, because directory_files_internal calls file-attributes to
get the attributes, including size.

Are the offending files larger than 4GB, by any chance?  If so, this
is expected: the emulation of `stat' we use simply doesn't support
such large files, since the relevant field of the `stat' structure is
32-bit wide.  To support such large files we will need to write stat64
and use 64-bit integers.  I don't expect this to happen before v22.1
is released.
