I think your problem may be the location of libgcc_s.so.1. libc.so is
not linked against libgcc_s.so.1, but all other DSOs are. When you
run ./bug-iconv1, some DSO loaded by ./bug-iconv1 has to find
libgcc_s.so.1 somewhere. I have
# ls -l /lib/libgcc_s* /usr/lib/libgcc_s*
-rw-r--r-- 1 root root 191044 Jul 2 14:27 /lib/libgcc_s-3.0.1-20010702.so
-rwxr-xr-x 1 root root 189314 Jul 3 17:01 /lib/libgcc_s-3.0.1-20010703.so
lrwxrwxrwx 1 root root 26 Jul 3 17:01 /lib/libgcc_s.so.1 -> libgcc_s-3.0.1-20010703.so
lrwxrwxrwx 1 root root 23 Jul 2 14:27 /usr/lib/libgcc_s.so -> ../../lib/libgcc_s.so.1
I think it is one way to deal with libgcc_s.so.1 on Linux.
