Create a directory, a file and a shortcut in the file system:

cd
mkdir -p path/to/long/directory/in/file/system
echo "hello" > path/to/long/directory/in/file/system/file
ln -s path/to/long/directory/in/file/system/ shortcut

In emacs

C-x C-f shortcut
M-x grep <ret> hello * <ret>

in the output mouse-1 on

file 1:hello

Then type: C-x C-b

Then you see that the filename of the file found in the grep output is 
~/path/to/long/directory/in/file/system/file

not ~/shortcut/file as you would have expected, and how it was before in
emacs version 27.1. Same thing happens in emacs 29.4.

I fixed this bug by removing two calls to file-truename in the
function compilation-find-file-1 and one call to the same function in
compilation-find-file (both functions in lisp/progmodes/compile.el)
