I can't reproduce this actually, but it seems clear that we do apply the umask
when --preserve=mode (-a) is
passed.
Curiously files get chmod()ed twice:
root@jak-t14-g3:~# rm -rf b && strace -e chmod coreutils cp -a a b && ls -lh a b
chmod("b/file", 0100700) = 0
chmod("b/file", 0100775) = 0
chmod("b/directory", 040775) = 0
chmod("b/", 040755) = 0
+++ exited with 0 +++
a:
total 0
drwxrwxr-x 1 root root 0 Jul 29 13:15 directory
-rwxrwxr-x 1 root root 0 Jul 29 13:11 file
b:
total 0
drwxrwxr-x 1 root root 0 Jul 29 13:15 directory
-rwxrwxr-x 1 root root 0 Jul 29 13:11 file

Bug description:
The installed tests are not happy in Questing,
https://autopkgtest.ubuntu.com/packages/g/gdk-pixbuf
Debugging it seems like something went weird with the build
$ ls -ld /usr/libexec/installed-tests/gdk-pixbuf/test-images/*
drwx------ 2 root root 4096 Jul 28 12:15
/usr/libexec/installed-tests/gdk-pixbuf/test-images/fail
drwx------ 2 root root 16384 Jul 28 12:15
/usr/libexec/installed-tests/gdk-pixbuf/test-images/gif-test-suite
drwx------ 2 root root 4096 Jul 28 12:15
/usr/libexec/installed-tests/gdk-pixbuf/test-images/randomly-modified
Those directories are 700, but they are 775 in Debian for the same source and
in the previous Ubuntu build. Unsure what went wrong, maybe some rust coreutils
problem?
Rebuilding in a ppa shows the same result...
