>Description:
When compiling to byte-code source with anonymous classes GCJ produces code which causes verifier errors with Sun's interpreter.



Note: this is stopping me reporting another anonymous classes bug for which I'm trying to produce a good test case.
>How-To-Repeat:
Compile the attached code thus:



   gcj -C -d . -classpath . A.java test.java



And then execute:



   java test



With GCJ you get this:



Exception in thread "main" java.lang.VerifyError: (class: test$1, method: <init> signature: (Ltest;Ljava/lang/String;IZ)V) Expecting to find object/array on stack

        at test.main(test.java:15)



With Sun's javac it compiles and runs quite happily. You should see the following output:



some overridden value
