    Object o1;
    int  type;
    public Foo  foo(Foo[] argv) {
        if (argv.length == 2 && ((String)argv[0].o1).equals("Arg0") &&
                argv[1].type == Foo.BAR) {
        }
    }
}

State-Changed-Why:
    I tried this with the latest egcs gcj and libgcj,
    and I didn't get a segv.  Instead I got correct
    error messages about the program (which has errors).
    
    Can you try this?  If so, please do so and get back to me.
    If not, tell me and I will just close this PR.
    
    Thanks.
