gij with gcc 2.95.2 (was: Re: internal error - SP mismatch)

[James CE Johnson]

Ok...

This works:
    [jcej@node04 T3]$ rm -f *.so *.class
    [jcej@node04 T3]$ gcj -C HelloWorld.java
    [jcej@node04 T3]$ gij HelloWorld
    Hello World

As does this:
    [jcej@node04 T3]$ rm -f *.so *.class
    [jcej@node04 T3]$ gcj -shared -o HelloWorld.so HelloWorld.java
    [jcej@node04 T3]$ gij HelloWorld
    Hello World

Both of those with this trivial HelloWorld.java:
    public class HelloWorld
    {
       public static void main(String args[])
       {
          System.err.println("Hello World");
       }
    }

Now I want to simulate using an object in some random .class file.  So I create:
class Foo
{
        public int Bar()
        {
                System.err.println("Foo::Bar");
                return 0;
        }
}

And change main():
public class HelloWorld
{
   public static void main(String args[])
   {
      System.err.println("Hello World");
      Foo foo = new Foo();
      foo.Bar();
   }
}

Compile everything to .class and we have success:

[jcej@node04 T3]$ rm -f *.so *.class
[jcej@node04 T3]$ gcj -C HelloWorld.java
[jcej@node04 T3]$ gcj -C Foo.java
[jcej@node04 T3]$ gij HelloWorld
Hello World
Foo::Bar

Try mixing native binary & .class and we have failure:

[jcej@node04 T3]$ rm -f *.so *.class
[jcej@node04 T3]$ gcj -C Foo.java
[jcej@node04 T3]$ gcj -shared -o HelloWorld.so HelloWorld.java
[jcej@node04 T3]$ gij HelloWorld

So... What did I do wrong this time?
