Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |ASSIGNED Last reconfirmed| |2013-12-09 Ever confirmed|0 |1 --- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> --- Uhhm, looks like that in 2007 (!) when I implemented the resolution of DR 596 I failed to also update the behavior of overflow and xsputn to the effect that, essentially, ios_base::app implies ios_base::out. Seems easy to fix.
