Created attachment 172421 [details]
source code using alternate return
Comment 2 Matthew Fotzler CLA 2010-06-24 10:48:52 EDT 
Will need to fix control flow graph when this support is added.
Comment 3 Jeffrey Overbey CLA 2011-03-17 11:23:17 EDT 
This appears to be fixed in HEAD/7.0 -- I'm not sure exactly when it was fixed though...
