Thanks a lot! Actually, I think you can also make the BugReporterVisitor approach work similarly. When you create the visitor, you would pass the symbol associated with the filedescriptor to the visitor and the visitor would track back to the function that created the said symbol. I am fine with both the set and the visitor approach I just want it to be symbol based as opposed to matching the AST.
