Subject: [Bug java/23620] New: Segfault compiling inner interfaces

I'm getting an ICE with gcc 4.0.1 that I've reduced to the following test case
with three classes, in A.java, B.java, and C.java, respectively:

public class A  {
    public interface AInt { void methA(); }
}
public class B implements A.AInt {
    void methA() { }
    public interface BInt { void methB(); }
}
public class C implements B.BInt {
    void methB() { }
}

$ gcj -C A.java
$ gcj -C B.java
$ gcj -C C.java
C.java:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.0/README.Bugs>.

However, doing

$ gcj -C A.java B.java C.java

gives no error.

Sorry if this is already known, but I couldn't find a similar bug already reported.
