bug#57301: 28.1; 12 unexpected test results on emacs 28.1

[gitmux]

Dear GNU Emacs,

        When executing `make check`, there are 12 unexpected tests.
The configuration, compilation, and test occurs with `compile.sh'.
`output.txt' is the resulting output. The other four attached files
contain the `unexpected results'. Version 28.1 is acquired from
`mirror://gnu/emacs/emacs-28.1.tar.xz'.
