--- Comment #5 from Florian Weimer <fweimer at redhat dot com> ---
Yes, the symbol version is missing:
$ eu-readelf -s libbar.so | grep memmove
2: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UNDEF memmove
The static linker invocation is incorrect. If you link in libc.so.6, the
problem goes away, “-z now” or no “-z now”.
Considering that the lack of symbol versions makes these objects very much
undefined anyway, is there anything here we need to fix in glibc ld.so?
