Catch Me If You Can: LLVM back-end cannot catch all exceptions

[WayBack] Catch Me If You Can:

the LLVM backend cannot return from a hardware exception (like AV) if the hardware exception is raised directly within a try...except block. It can only safely return if there is a function (method) call within the try...except block.
