[xmlvm-users] GC of inner classes

[Panayotis K. <pan...@pa...>]

Is it possible to give me some hints, how the GC is working with inner classes?

I have this scenario:

A class (level 0) has an anonymous inner class (level 1) , which in turn has inside another anonymous inner class (level 2).

The lifetime is like this:

i) Class of level 0, creates a level 1 class
ii) Level 1 class creates level 2 class and gives its reference back to level 0 class
iii Level 0 class removes all usage & references of level 1 class (the item should be released)
iv) Level 2 class starts executing, while requiring some variables of level 0 class.

If I am correct, currently XMLVM is able to access information of level 0 class to the level 2 class through the level 1 class.
If this is so, a segmentation fault would appear.


1) Is this situation handled correctly by the C backend?

2) In ObjC backend, I can see that the inner classes hold a weak reference to the parent class. What if we establish a strong reference between the parent and the inner class ?
