javac -target 1.1 stat.java
gcj -c stat.class
3.4.1: stat$B.java:0: error: non-static method 'stat$B.internal_new_GC(int)'
overrides static method
3.5: stat.class:0: internal compiler error: in size_binop, at fold-const.c:1707
class stat {
public static void main(String[] a) {
stat s = new stat();
}
class B extends A {
public long internal_new_GC(int a) {
return 0L;
}
}
public abstract class A implements I {
}
public interface I {
public long internal_new_GC (int a);
}
}
(might be related to PR 15888, but that one is compiling .java source,
not .class)

I've investigated this a little.
This is another miranda method bug.
javac -target 1.1 emits an explicit redeclaration
of I.internal_new_GC in A. This declaration is
marked Synthetic.
In class.c:layout_class_method, we don't set the DECL_VINDEX
for a method if "DECL_ARTIFICIAL (method_decl)".
This means that when we try to set the vindex for
B.internal_new_GC, we do find a super_method, but the
super_method does not have an assigned vtable slot.
I believe the solution is to remove the test for DECL_ARTIFICIAL
when doing vtable layout. I'll test a patch.
