Default arguments for methods of subclasses not initialized. #189

What steps will reproduce the problem?

1. Compile the attached source with shedskin:

class Alpha:
    def __init(self):
        pass

    def func(self, value=True):
        print("value is:" + str(value))

class Beta(Alpha):
    def __init(self):
        pass

b = Beta()
b.func();

looking at the generated cpp code you can see that default_0 is set
but not used, while default_1 is not set but used.

void __init() {
    const_0 = new str("value is:");

    __name__ = new str("__main__");

    default_0 = True;
    cl_Alpha = new class_("Alpha");
    cl_Beta = new class_("Beta");
    b = (new Beta());
    b->func(default_1);
}

What is the expected output? What do you see instead?

"value is:True".  This is what cpython prints.

Instead I see "value is:False"

What version of the product are you using? On what operating system?

shedskin-mainline, on OSX

Please provide any additional information below.
