The pattern is clear:
https://tests.reproducible-builds.org/debian/history/isc-dhcp.html

I am also able to reproduce it locally.

Am I guessing correct that merged /usr is used in your
successful build?

libisc-export166: /lib/x86_64-linux-gnu/libisc-export.so.166.2.0
libbind-export-dev: /usr/lib/x86_64-linux-gnu/libisc-export.so

The .so symlink is dangling without merged /usr,
and in that case the static library is used instead.
