In PE builds of wine, there's no unwind info (as LLVM hasn't
implemented generating SEH unwind info for ARM yet).

On startup of wine, an exception of the type RPC_S_SERVER_UNAVAILABLE
is raised. In a PE build of Wine, the unwind would get stuck in
an infinite loop.

This still loops for a short while; after returning the error
STATUS_INVALID_DISPOSITION, KiUserExceptionDispatcher ends up
calling RtlRaiseStatus with this status, which then tries to
unwind again, getting stuck similarly. However by recursively
trying to unwind multiple times, the process crashes fairly soon
after running out of stack.
