           Summary: ICE compiling cross-package inherited constants
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: major
          Priority: P4
         Component: java
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: robin.garner@crsrehab.gov.au
                CC: gcc-bugs@gcc.gnu.org

gcj crashes with an ICE when compiling the following code (3 files):

P/a.java:
package P;
class a { static final int A = 2; }

P/b.java:
package P;
public interface b { static int B = a.A; }

Q/c.java:
package Q;
import P.b;
class c {
  static int x; { x = b.B; }  // Virtually any reference to b.B works here
}

gcj -c  P/a.java
gcj -c  P/b.java
gcj -c  Q/c.java
c.java:4: internal compiler error: Segmentation fault
Please submit a full bug report,

Configuration details follow:

The ICE is gone on the mainline but it is rejected unless you compile P/a.java and P/
b.java to *.class files.

./P/b.java:3: error: Can't access class `P.a'. Only public classes and interfaces in other 
packages can be accessed.
   public interface b { static int B = a.A; }
                                       ^
./P/b.java:3: error: Can't access package-private field `P.a.A' from `Q.c'.
   public interface b { static int B = a.A; }
                                        ^
2 errors
