2123 – Anonymous class crashes

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();
}

Fixed dmd 1.031 and 2.015
