--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
The reproducer in comment #2 is nicer because it will have the .dwo files,
which need to somehow be handled.
The testcase from the description has been executables linked with some object
files which were compiled with -gsplit-dwarf, because it does have some
skeleton units (and a .debug_addr section) but is missing the .dwo files (or
.dwp archive) containing the split unit sections. Without the split units you
cannot resolve the skeleton units (the split units will refer to the
.debug_addr table).

--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
This can easily be reproduced with:
...
$ gcc hello.c -gsplit-dwarf -g -c
$ gcc hello.o -g
$ dwz a.out
dwz: a.out: Unknown debugging section .debug_addr
