--- Comment #3 from Ian Lance Taylor <ian at airs dot com> ---
The default value for --with-boot-ldflags is "-static-libstdc++ -static-libgcc"
(set in the top level configure.ac file).  When the g++ driver sees
-static-libstdc++, it puts -Bstatic before -lstdc++ and puts -Bdynamic after
it.  So when you build with --disable-static, the effect is that go1 is linked
against some other libstdc++ that it finds on the system, not the one that was
just built.  So it is not surprising that something went wrong.

I would say that if someone configures with --disable-static, we need to change
the default value of --with-boot-ldflags.
