My bash script stopped working (hangs) after upgrading to v3.7

Given this script:

#!/bin/bash

# https://github.com/koalaman/shellcheck/wiki/SC2044
while IFS= read -r -d '' file; do
  echo -n checking "${file}"

  # This works on alpine 3.6 but hangs on 3.7 and edge.
  if stat -c %F "${file}" | grep -qE '^directory$'; then
    echo " DIRECTORY"
  else
    echo
  fi

done < <(find /etc -maxdepth 1 -print0)

It works on alpine 3.6.

However, it hangs on alpine 3.7 and edge after it prints

checking /etc
