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 typetraits::int_type while the return type of sync() is int.

Proposed resolution:

In 31.7.5.4[istream.unformatted], paragraph 36, change "returnstraits::eof()" to "returns-1".
