--- Comment #23 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-07-13 15:20:23 UTC --- To be honest, isn't a real regression, because you are using -std=gnu++0x, and simply in 4.4.x we had no C++0x conforming std::stable_sort. In general, my feeling is that the fix is too invasive for 4.6.x, but please stress it as much as possible and if in a couple of weeks no regressions will appear we can reconsider a backport.
