Hi Everybody,

in the TC1 amended standard, a new footnote has been added to the
description of funtion codecvt::do_encoding (22.2.1.5.2 para 7, footnote
227), saying that: "if encoding() returns -1, then more than
max_length() characters may be consumed when producing a single internT
character and additional externT elements may appear at the end of a
sequence after those that yield the final internT character."

I could not find an defect report about this issue here
<http://std.dkuug.dk/jtc1/sc22/wg21/docs/lwg-active.html>. Can someone
explain the rationale for this addendum?

Maybe I'm missing something, but isn't this footnote in plain
contradiction with the definition of max_length()?

Thanks,

Alberto Barbati
