Linkfailures on amd64 with -fvisibility-inlines-hidden and the libstdc++ headers or symbols

Therefore, to your best knowledge, the problem occurs only on x86_64? I'm
trying to figure first whether something is wrong in the generic code and,
moreover, whether it's really the library or something else in the toolchain
(I suppose you are using up to date binutils?)

Thanks,
