I can reproduce it with:
emacs -Q
M-: (load "~/.emacs.d/elpa/rust-mode-20190517.2037/rust-mode.el")
and then
M-x compile
cargo build <-- command to run rust code compilation
Interesting, that `cargo build` works in deterministic way, it produces
the same output for the same code set on the Rust language.
So the content of *compilation* buffer is always the same,
except of course:
Compilation started at ...
Compilation exited abnormally with code 101 ...
But sometimes it renders ok, sometimes bad.
And if I run
M-x compile
cat /tmp/saved-compilation-buffer-content.txt
the *compilation* rendering is always fine, no errors.
