This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 110b. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
In 12.2.4 [over.match.best] paragraph 1, bullet 4 of the second set of bullets, there is a cross-reference to 9.4 [dcl.init] and 126.96.36.199 [over.match.conv] . I believe it should also reference 188.8.131.52 [over.match.ref] . I think the phrase "initialization by user-defined conversion" was intended to refer to all initializations using user-defined conversions, and not just the case in 184.108.40.206 [over.match.conv] . Referring to only 220.127.116.11 [over.match.conv] suggests a narrower meaning of the phrase.
18.104.22.168 [over.match.copy] , although it does deal with initialization by user-defined conversion, does not need to be referenced because it deals with class —> class cases, and therefore there are no standard conversions involved that could be compared.
