bug#38648: 27.0.50; Emacs `compile' command does not handle remote (over TRAMP) file name correctly |

Re-produce steps:
1. `find-file' to my project root directory on a remote machine,
namely, "/scp:vm00:pmdk-balloon/".
2. `M-x compile', and give compile command "make".
3. (Previously I have injected some typos in some of my source files,
say "obj.c").
4. In the *compilation* buffer, the "obj.c" file appears. But when I
click the underlined text (or <RET> on it), an error occurs in the
minibuffer:
"Find this error in (default obj.c):
/scp:vm00:/System/Volumes/Data/home/fan/pmdk-balloon/src/libpmemobj"
The "/System/Volumes/Data/" is actually a path on my local machine.
5. To further confirm, I use `C-u C-x =' on the underlined text in the
*compilation* buffer. The "compilation-message" text property shows:
#s(compilation--message
(nil 42
(("../common/vec.h"
"/scp:vm00:/System/Volumes/Data/home/fan/pmdk-balloon/src/libpmemobj")
nil
(42 #1))
nil nil)
0 nil)
It appears that when compile.el was handling the remote path, it
mixed-up part of my local machine path with the
remote machine path, resulting the error.
I use Edebug to instrument `compilation-get-file-structure' and
then `file-truename' to find when my local path "/System/Volumes/Data/"
is inserted, here is a backtrace:
lines started with a "*" is what I think important.

Then I find that in my environment, `(file-symlink-p "/home")' is
evaluated to "/System/Volumes/Data/home". Now I stuck here since I know
little about TRAMP and how a remote file path should be handled.
Do you have any suggestion or idea to fix this bug? Thanks in advance
for your time.
