11146,iostreams seekpos/seekoff must not throw exceptions,stheophil@…,Jonathan Turkanis,"Currently, `direct_streambuf<T, Tr>::seek_impl` throws `bad_seek()` exception on invalid input.

The current standard draft N4296 says in section 27.8.2.4 about `seekoff`:

''If the positioning operation fails, or if the constructed object cannot represent the resultant stream position, the return value is pos_type(off_type(-1)).''

At least the MSVC STL implementation does not expect pubseekoff/seekoff to throw, thus does not catch the exception and the bad_seek() exception may leak to the caller even though ios_base::exceptions() is 0.
