    I've checked in the fix.
    It will appear in gcc 3.2.
    (Perhaps it should be ported to 3.1.1?)

Bug submitter got gcj to segfault:

% gcj-3.1 Foo.java 
Foo.java:2: 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.

The contents of Foo.java are:

public class Foo {
        private foo;
}

Notive how the type of field foo is missing.  gcj should report an
error for this file, but it shouldn't crash.  It happens somewhere
in java_parse().  I don't have more information because building
a version with debugging symbols was too fiddly and frustrating.
