This test case crashes on 1.030 but not
on 1.029 and 1.028.

I had this mentioned in bug #2067, but it was silently closed, so it is perhaps better to do this into its own bug report.

module test;
extern(C) int printf(char*,...);

class I {
    public abstract void callI();
}

class C  {
    private int index;
    void test1(){
        printf( "ok\n" );
    }
    I test(){
        auto i = new class() I {
            public void callI() {
                test1();
            }
        };
        return i;
    }
}
void main () {
    auto c = new C;
    auto i = c.test();
    i.callI();
}
