thanks
Thanks for uploading a better fix for the RC bug #481247.
However, the non-RC bug I reported still exists: if "file -m" is used to
select an alternative source of magic patterns, and that source is a
directory, then the order in which they are applied is non-deterministic,
since it depends on the order in which readdir() lists files.
With hindsight, I should have filed #488562 as minor, since using "file -m"
like this is rare (at least if you use either your solution to #481247,
or mine, to avoid needing it during the package build). Correcting that now.
I haven't been able to reproduce this bug in a minimal way (I don't have
a filesystem that re-orders readdir() on demand :-) but here's an
illustration that it still exists in 4.24-4.
libRuby.so.5.18 is the same file used to reproduce #481247, ~/tmp/file-4.24
is the unpacked source code of the package, and ~/tmp is on an ext3 filesystem
with hashed directories.

Commentary:
[1] this result is correct
[2] but this result, from input that ought to be equivalent, is wrong -
that's what this minor bug is about
[3] on the other hand, #481247 has indeed been fixed, so the package is no
longer RC-buggy
