--- Comment #17 from Nach <nachms+gcc at gmail dot com> ---
I just tried my above test case on RHEL6 without an up to date libstdc++ but
with glibc 2.12, and the binary runs just fine.

I double checked my old build system which does not produce these symbols, and
I see it uses the following:

Configured with: ../src/configure -v --with-pkgversion='Debian 4.6.3-4'
--with-bugurl=file:///usr/share/doc/gcc-4.6/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr
--program-suffix=-4.6 --enable-shared --enable-linker-build-id
--with-system-zlib --libexecdir=/usr/lib --without-included-gettext
--enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.6
--libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu
--enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object
--enable-plugin --enable-objc-gc --with-arch-32=i586 --with-tune=generic
--enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu
--target=x86_64-linux-gnu
Thread model: posix
gcc version 4.6.3 (Debian 4.6.3-4)

Note the --enable-gnu-unique-object. Also the system uses glibc 2.13.

Any reason why this old build setup does not use these glibc unique symbols
even though every indication is that it should?
