Why not?  If the location is a locexpr, i.e. pseudo range [0,-1) then it
shouldn't complain, sure.  But if it's a location list and the list has
entries outside the scope of the function, that sure seems suspect to me.
Perhaps you can cite an example of a valid case getting a warning.


Thanks,
Roland
