Discussion:
The Effects clause for sync() (27.6.1.3, paragraph 36) says that it "calls rdbuf()->pubsync() and, if that function returns -1 ... returns traits::eof()."
That looks suspicious, because traits::eof() is of type traits::int_type while the return type of sync() is int.
Proposed resolution:
In 31.7.5.4 [istream.unformatted], paragraph 36, change "returns traits::eof()" to "returns -1".
