Unfortunately it does not. (I remembered to remove the
.bss alignment hack in my sparc copy reloc function before
testing).
Here is the 'readelf -a' output from the executable of one such case
that fails, two_file_shared_2_test.
I've also put up the binaries that compose this test case at:
http://vger.kernel.org/~davem/two_file_shared_2.tar.gz
in case that helps diagnose this further.
Thanks!
