That is only a serious problem if the two versions are not binary
compatible.  I suspect that the symbols in the program body are
always used, even in order to satisfy internal dependencies within
a loaded library.

(I used to ensure that the only global symbols in a shared library
where those of the external interface, and that those symbols where
never referenced internally.  Otherwise havock ensues anyway.)

Remember where is no requirement for a shared library to actually
require any of libc.
