Bug#129613: gcj-3.0: segmentation fault on incorrect input

[Richard Braakman <dark@xs4all.nl>]

Package: gcj-3.0
Version: 1:3.0.3-1
Severity: minor

I got gcj to segfault:

% gcj Foo.java 
Foo.java:2: Internal error: Segmentation fault
Please submit a full bug report,

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.

Oh, I did run gcj -v as well:

%  gcj -v Foo.java
