--- Comment #12 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-03-13 13:11:38 UTC --- Ian, I see you are returning to this old issue. Really, today I don't have a strong opinion, if you are willing to post to the mailing list a patchlet (I think both std/ostream and bits/ostream.tcc have to be touched + adjusting the testsuite) outputting "(null)" instead of setting badbit I have no objections (to be clear, I didn't decide or existing impl defined behavior, thus we serious reasons to hear the mailing list before applying it). Only, I'm not sure what we want to do for the "primary" overload, operator<<(basic_ostream<_CharT, _Traits>&, const _CharT*), maybe just do nothing, I don't know, really, up to you (and the mailing list, again).
