For me, no compilation arguments (I assume that's what you mean by keys).
As stated it compiles and runs okay in my app (Like Kraymer says, most of the time a crash in KA2 for me means it compiled okay, I have many many more examples where the code compiles fine, but crashes KA2)
Target is... all of them.
I'm using a Radeon 5670. KA2 version is 2.1.880
Let me know if I can be any more help
