Discussion:
The Effects clause in 31.5.4.4[iostate.flags] paragraph 5 says that thefunction only throws if the respective bits are already set prior tothe function call. That's obviously not the intent. The typo ought tobe corrected and the text reworded as: "If (state &exceptions()) == 0, returns. ..."
Proposed resolution:
In 31.5.4.4[iostate.flags] paragraph 5, replace "If (rdstate() &exceptions()) == 0" with "If ((state | (rdbuf() ? goodbit : badbit))& exceptions()) == 0".
[Kona: the original proposed resolution wasn't quite right. We really do mean rdstate(); the ambiguity is that the wording in the standard doesn't make it clear whether we mean rdstate() before setting the new state, or rdsate() after setting it. We intend the latter, of course. Post-Kona: Martin provided wording.]
