[llvm-dev] How to catch EXCEPTION_ACCESS_VIOLATION exceptions on win64

[Reid Kleckner via llvm-dev]

I would not expect you to be able to catch any exceptions originating from
code JITed by LLVM on Win64. Nobody has implemented the code to register
the unwind data necessary to do this. The linked bug describes the steps
necessary to implement this functionality.
