Suppose I'm watching a question, while doing some thinking and pondering an answer someone else comes up with a similar answer. I've no issues with that. But when that answer or comment make clearly-wrong statements as fact, how can I address them? In other words, even if the answer or comment is helpful, how do I address statements or coding remarks that are completely wrong (as in against the C++-spec kinda-wrong) when those issues have nothing to do with the original question?
For example: This question deals with a person's failure to get their configuration corrrectly for linking in object code. During the course of the q+a, someone makes a completely inaccurate statement about derived classes of base classes with pure virtual functions and/or virtual destructors being required to implement a destructor in the derived class. This is NOT true, but I could only post why it isn't in another answer (tried saying it in comment to no avail).
I don't think it is right of me to address that in an answer to the question (though I think the question author could probably learn a LOT from the post anyway), but is there some "correct" place to address this kind of thing?
THank you in advance. Cooler heads prevail. =P
