It's really hard to believe that those two examples work differently.
I think more likely you're up against some procedural error that you
are misinterpreting to suggest that adding an unused local variable
would really make a difference.
One thought that comes to mind is that as of recent releases, the
only way to load a modified .so into the backend is to start a fresh
session. So if you recompiled and then tried to do a CREATE FUNCTION
in a backend that had already loaded the previous version of the .so,
you could get an error like that. Any chance it's that?
