bug#36001: 26.2; compile-mode.el/compilation-mode spontaneous behaviour

[Evgeniy Dushistov <dushistov@mail.ru>]

Hi,

compile-mode.el (compilation-mode) works in really spontaneous way.

I run compilation via:

(defun rust-compile ()
  "Compile using `cargo build`"
  (interactive)
  (compile "cargo build"))
 
Sometimes errors are highlighted, sometimes aren't.
For example I run compilation, and the first error is not highlighted:

Then I switch buffer '*compilation*' and run M-x compilation-mode,
and error is highlighted in the right way:

Also jump to the error via C-x ` sometimes doesn't work (emacs insitead of jump to code,
asks where find source file), but after I would switch to '*compilation*' and
run M-x compilation-mode, C-x ` works again. 

These are spontaneous errors, I have ~10 good cases,
when all works fine vs 1 bad case, when rending or jump to source location works
only for subset of errors/warnings.
