With kernel 147440-01, all programs linking against libstdc++.so.6 will fail to start, complaining about unresolved symbols. LD_DEBUG=symbols reveals that the symbols are seen as hidden: $ LD_DEBUG=symbols ldd -r libstdc++.so.6.0.14.orig 2>&1 | grep check_lengthEjjPKc 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; lookup in file=/usr/lib/lddstub [ ELF ] 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; lookup in file=./libstdc++.so.6.0.14.orig [ ELF ] 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; hash index=3718; version=32770; skipping symbol with GNU version hidden bit set in file=./libstdc++.so.6.0.14.orig 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; lookup in file=/lib/libm.so.2 [ ELF ] 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; lookup in file=/home/pub/lib/gentoo-prefix/lib/libgcc_s.so.1 [ ELF ] 21967: symbol=_ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc; lookup in file=/lib/libc.so.1 [ ELF ] symbol not found: _ZNKSbIwSt11char_traitsIwESaIwEE15_M_check_lengthEjjPKc (./libstdc++.so.6.0.14.orig) Workaround from the URL forum thread helps: /usr/bin/elfedit -e 'dyn:delete versym' libstdc++.so.6 libstdc++.so.6-alt

We do not use gcc-4.2 any more in Prefix: Still a problem with current gcc (>=5.3)?
