Description Kalle Olavi Niemitalo 2005-01-30 09:45:33 UTC
A GCC checked out from CVS on 2005-01-29 compiles the following
code without complaint, generating a g() that accesses Outer.x:

class Outer {
    int x;
    void f(Object x) {
        class Inner {
            int g() {
                return x;

The parameter with the same name should shadow the field, and GCC
should then report an error because the parameter is not final
and even has the wrong type.

$ gcj -v -C

All gcj front end bugs have been fixed by the gcj-eclipse branch merge.
I'm mass-closing the affected PRs.
If you believe one of these was closed in error, please reopen it
