Summary: wifstream conversion errors result in wrong rdstate()
Product: gcc
Version: 3.4
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libstdc++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: peturr02 at ru dot is
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
When input using wifstream fails because the file contains an invalid
byte sequence, eofbit, but not badbit, is set in rdstate(). The
description of the rdstate() flags indicates badbit should be set on
conversion errors, but eofbit should only be set if end of file has
been reached.

Hi. Could you please explain in little more detail? The code mentions
27.6.1.1 p3 (eofbit) (and 27.6.1.3 p2 adds failbit)
Thanks!

... perhaps you believe that rdbuf->sbumpc() should throw an exception in this
case?

I think that is the only useful solution. Note that there are other reasons
for doing that, such as the one mentioned in PR 11603: If sbumpc() returns
eof() on conversion errors, showmanyc() must always return 0. If showmanyc()
is to be useful, sbumpc() must throw an exception on conversion errors.
