Hi,
Here is a reproducible GC bug with kaffe HEAD. It's a regression, as it does
not happen with 1.1.5.
This happens when compiling two small programs with the Nice compiler's
testsuite. Therefore, you'll need the Nice compiler, precisely the nice.jar
file. I've reproduced with several versions, including 0.9.10 which is in
Debian at the moment. http://nice.sf.net/nice.jar should also do.
Here are the instructions to reproduce the bug. You need the bug.testsuite
file as shown. Note that you need to specify the location of nice.jar twice.
$ cat bug.testsuite
/// PASS
/// package a
/// Toplevel
abstract class A implements javax.swing.Action {
putValue(x, y) {}
}
/// package b import a
/// Toplevel
<T> void putValue(javax.swing.Action, String, T) =
native void javax.swing.Action.putValue(String, Object);
public class Flow4JEditPartFactory implements javax.swing.Action {
putValue(editPart, model) {}
}
/// PASS
/// package lib
/// Toplevel
public class A {
public void foo() {}
}
/// package a
/// Toplevel
class A<T> = native lib.A;
<T> A<T> A() = native new lib.A();
<T> void foo(A<T>) = native void lib.A.foo();
/// package b import a
{}
/// package c import b
new lib.A().foo();
