--- Comment #24 from André Wöbbeking <Woebbeking at web dot de> 2013-03-15 09:25:02 UTC --- OK, I read some explanations in the duplicates but still don't know why this should be valid code. IMO it makes no sense to write A:A:A:B and given the facts that 1) people don't write this intentionally 2) people expect this to be invalid (see number of duplicates) 3) some other compiler don't compile this couldn't you at least give us a warning (e. g. with -pedantic)?
