Thanks for the report!

That's weird. I cannot reproduce this. It works in Debian (but that
could imply some hidden dependency), and I just spawned an alpine:latest
Docker image, and it passes there too with what's currently on git HEAD:

  ,---
  /src/dpkg # cat /etc/alpine-release
  3.17.0
  /src/dpkg # apk --version
  apk-tools 2.12.10, compiled for x86_64.
  /src/dpkg # make -C scripts/ check
  […]
  ./t/merge_changelogs.t ......... ok
  ./t/mk.t ....................... ok
  All tests successful.
  Files=47, Tests=24295, 11 wallclock secs ( 1.11 usr  0.12 sys +  8.06 cusr  1.34 csys = 10.63 CPU)
  Result: PASS
  make[2]: Leaving directory '/src/dpkg/scripts'
  make[1]: Leaving directory '/src/dpkg/scripts'
  make: Leaving directory '/src/dpkg/scripts'
  `---

If you can point a way for me to reproduce, I'm happy to dig further.

Thanks,
