Hey!
I think I have run in to a strange bug, with either vala or glib, and
I'd like to check if I'm doing something wrong.
My library versions:
valac --version: Vala 0.9.7.143
dpkg -l 'libglib2.0-0': 2.24.1-0ubuntu
Attached is a test case that illustrates the problem I am having, but
basically when I use an integer as a generic argument, I get really
strange results on 64bits while on 32bits everything works well.
Thanks for any help!
Sam
These are the outputs I get when I try and run the program:

Array Slice
Not Boxed: 1 0 4 0
Boxed: 1 4 8 2
For-loop Copy
