--- Comment #12 from Zbigniew Jędrzejewski-Szmek <zbyszek at in dot wa

So, once again (with patched ld installed as /usr/bin/ld):
(gold, a versioned, b unversioned)
$ gcc -shared -o liba.so liba.c -fPIC -Wl,--version-script=liba.sym
-Wl,-fuse-ld=gold
$ gcc -shared -o libb.so libb.c -fPIC -L. -la -Wl,-fuse-ld=gold
$ LD_LIBRARY_PATH=. gcc -L. -lb test1.c -o test1 -Wl,-fuse-ld=gold
$ LD_LIBRARY_PATH=. ./test1
Segmentation fault (core dumped)
(gold, a versioned, b versioned)
$ gcc -shared -o liba.so liba.c -fPIC -Wl,--version-script=liba.sym
-Wl,-fuse-ld=gold
$ gcc -shared -o libb.so libb.c -fPIC -L. -la -Wl,--version-script=libb.s
ym
-Wl,-fuse-ld=gold
$ LD_LIBRARY_PATH=. gcc -L. -lb test1.c -o test1 -Wl,-fuse-ld=gold
$ LD_LIBRARY_PATH=. ./test1
bla bla
(bfd, a versioned, b versioned)
$ gcc -shared -o liba.so liba.c -fPIC -Wl,--version-script=liba.sym
-Wl,-fuse-ld=bfd
$ gcc -shared -o libb.so libb.c -fPIC -L. -la -Wl,--version-script=libb.s
ym
-Wl,-fuse-ld=bfd
$ LD_LIBRARY_PATH=. gcc -L. -lb test1.c -o test1 -Wl,-fuse-ld=bfd
$ LD_LIBRARY_PATH=. ./test1
Segmentation fault (core dumped)
(bfd, a versioned, b versioned)
$ gcc -shared -o liba.so liba.c -fPIC -Wl,--version-script=liba.sym
-Wl,-fuse-ld=bfd
$ gcc -shared -o libb.so libb.c -fPIC -L. -la -Wl,--version-script=libb.s
ym
-Wl,-fuse-ld=bfd
$ LD_LIBRARY_PATH=. gcc -L. -lb test1.c -o test1 -Wl,-fuse-ld=bfd
$ LD_LIBRARY_PATH=. ./test1
bla bla
So the unversioned libb fails to produce a working binary with either linke
r.
With your patch, versioned libb works with both linkers.
I also have more complicated test-case: systemd-logind.so in the systemd
project, from which
this testcase was derived. It is versioned and works with your patch. Thank
s!
