Is that generally true? I mean, first of all, false positives are a
well-known phenomenon with this static analyzer (the Web page at llvm.org
talks about this). Second, they do no harm. I get a false positive in *any*
of my apps that uses NSURLConnection, for example:
NSURLConnection* con = [[NSURLConnection alloc] initWithRequest:req
delegate:self];
That triggers a "potential leak" warning. Well, of course it is a
*potential* leak. But it isn't a *real* leak, because I happen to know that
I'm going to release this object in either connection:didFailWithError: or
connectionDidFinishLoading:. (My code and memory management come right out
of Apple's own examples here.) I know how NSURLConnections work; the static
analyzer doesn't. But I would hardly call that a bug.
