[ Reported to the Debian BTS as report #152501.

Rechecked with gcc-3_1-branch 20020606.

Hello, I found code on which gcj crashes.  I reduced it to a minimal test
case, and in the process found a workaround, so I'm happy :)  But here's
the test case:

File Main.java:
import pkg.sub;

class Main {
        public static void progressMessage(String msg) {
                System.out.println(msg);
        }

        public static void main(String[] args) {
                new sub();
        }
}


File pkg/sub.java:
package pkg;

public class sub {
        public sub() {
                        Main.progressMessage("Foo");
        }
}


Compilation:
% gcj-3.1 -I. -c Main.java -o Main.o
% gcj-3.1 -I. -c pkg/sub.java -o pkg/sub.o
pkg/sub.java:5: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

I think the problem is also present upstream, because I got the same crash
with a non-debian version of gcj 3.1.  Changing "class Main" to
"public class Main" will make the crash go away.
