Hello, Since commit r195676[1], it looks like libstdc++-v3/src/c++11/hashtable_c++0x.cc is missing an explicit instantiation for std::lower_bound. This leads to libstdc++.so having the symbol for that (missing) instantiation be undefined, thus preventing executables from being linked with libstdc++. The patchlet below seems to fixed the issue for me. Boostrapped and tested on x86_64-unknown-linux-gnu.
