unique_shared_ref.s
Instructions (as tested on Fedora 18 x86_64):
$ as unique_shared_ref.s -o unique_shared_ref.o
$ as unique_shared.s -o unique_shared.o
$ ld -shared -o unique_shared_ref.so unique_shared_ref.o
$ ld -o unique_shared_ref unique_shared_ref.o unique_shared.so
$ readelf -s unique_shared_ref | grep UNIQ
1: 0000000000000000 0 OBJECT UNIQUE DEFAULT UND b
11: 0000000000000000 0 OBJECT UNIQUE DEFAULT UND b
$ readelf -h unique_shared_ref | grep ABI
OS/ABI: UNIX - System V

Either the ABI should be set to GNU, or GNU_UNIQUE shouldn't be used for the
symbol reference.
