JFF crashes VM on invokeN0 on i386 and on armhf alltogether

[aploese]

On an Linux i386 Openjdk-19 this code crashes the VM on invokeN0
On Linux armhf Openjdk-11 and Openjdk-19 even invokeI0 crashes.

    public static void main(String[] args) {
        final CallContext CC = new CallContext(Type.SINT32, Type.VOID);
        final Library LIB = Library.getDefault();
        long address = LIB.getSymbolAddress("getpid");

        System.out.println("JFFI Test call getpid() via invokeI0: ");

        int result = (int) Invoker.getInstance().invokeI0(
                CC,
                address);

        System.out.println("JFFI Test -> getpid (invokeI0): " + result);

        System.out.println("JFFI Test call getpid() via invokeN0: ");

        result = (int) Invoker.getInstance().invokeN0(
                CC,
                address);

        System.out.println("JFFI Test -> getpid (invokeN0): " + result);

        System.out.println("JFFI Test call getpid() via invokeL0: ");

        result = (int) Invoker.getInstance().invokeL0(
                CC,
                address);

        System.out.println("JFFI Test -> getpid (invokeL0): " + result);
    }
