--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-03-29 10:08:20 UTC --- (In reply to comment #0) > I am not sure this is really a bug (is building libstdc++ at -O0 supported?), Yes, the --enable-libstdcxx-debug configure option builds an alternative libstdc++.so with -O0 (but I can't reproduce this when using that lib)
