--- Comment #2 from Dmitry G. Dyachenko <dimhen at gmail dot com> ---
gcc invocation can be simplified : -fno-semantic-interposition can be removed.
(was needed while creducing original testcase)

So,
$ g++ -fpreprocessed -O2 -flto -fPIC -DPIC -c -o a.o a.ii
$ g++ -fpreprocessed -O2 -flto -fPIC -DPIC -c -o b.o b.ii
$ g++ -flto -fPIC -DPIC -shared a.o b.o
