This is an instance variable which should always be accessible within
a method implementation.  If I add a local declaration, I get "local
declaration shadows ivar" warning.  That's absurd.

I included a minimal example that doesn't depend on gnustep-base in
the upstream report, and also pointed out the change that introduced
this bug.
