--- Comment #3 from Dima Tisnek <dimaqq at gmail dot com> ---
@Jonathan, arguably, `std::ifstream f("/");` should not through, as underlying
`open()` succeeds. No read call is made at that point. That was the nature of
bug  36564 They site ""current standard" at the time.

(Personally I'd prefer ifstream creation to fail, but I can live with that).

Successive read operations really ought to set some error bit.
