Well, I think the problem is not exposing a new symbol by itself, but __mb_sb_limit is being used in _ctype.h, in a form of __inline functions. Therefore, the change will break new binaries running on older systems. Personally I think this is acceptable, but maybe we could have a better way to avoid this, because the binaries are no longer backward compatible (i.e. you may have trouble running a program compiled for 6.3-RELEASE on 6.2-RELEASE, if it uses locale bits). As a workaround as discussed with rafan@ we have installed a workaround for now, which installs libc.so.6 before all other shared objects, which will make the problem invisible.
