If libstdc++ relies on ODR, then RTLD_DEEPBIND can break its assumptions, as
then the same symbol which is defined in multiple shared libraries can resolve
to different addresses (RTLD_DEEPBIND means first the dlopened library and its
dependencies, and only after it the global search scope, will be searched).

STB_GNU_UNIQUE object ought to cure it, though it is only in 4.5 (and 4.4-RH)
gcc and sufficiently new binutils and glibc are needed for it too.
