I have to say I'm interested in the PIC backend also. What I would do in this case is to write a failing test case and make it pass by fixing code (which I'm not sure exactly where). Can we talk more about this? Maybe goto to the devel list as recommended. Can you show a tiny program that reproduces the issue?
