troubleshooting pointers

With the current SRF patch, in certain circumstances selecting from a 
VIEW produces "Buffer Leak" warnings, while selecting from the function 
itself does not. Also the VIEW returns only one of the two expected 
rows. The same SQL function when declared as "... getfoo(int) RETURNS 
int AS ..." instead of "... getfoo(int) RETURNS *setof* int AS..." does 
not produce the warning. Any ideas what I should be focusing on to track 
this down? Does anyone have any favorite troubleshooting techniques for 
this type of problem?

Thanks,
Joe
