Interesting. If that's the case, then the documentation for that method is 
correct, the caller is responsible for freeing the returned object. I will file 
a bug report.

Thanks.

That's because it's missing a CF_RETURNS_RETAINED in the header for that 
method, which the analyzer needs to know what's going on.  I'm not sure there's 
any way around this other than filing a bug and hoping Apple updates the 
headers in the next release.

(Another example of this is SecTransformExecute in Securty.framework)
