--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-02-15 15:02:57 UTC --- Note that since 2010-12-16, when 4.5.2 has been released, only *very small* changes went into the 4_5-branch libstdc++ code: either the problem already existed at least *two months* earlier the date you indicated, or is a much more general build issue not specifically related to libstdc++ details... or the binutils you are using, I don't know. Please provide further details.
