On further inspection: the `xtrace` is not related to the problem:

script.sh
```
printf "FIRST LINE\n" > /dev/stderr
printf "SECOMD LINE\n" > /dev/stderr
```

```
$ bash script.sh
FIRST LINE
SECOMD LINE

$ bash script.sh 2> file && cat file
SECOMD LINE

$ file /dev/stderr
/dev/stderr: symbolic link to /proc/self/fd/2
```
