Reproducer cya_begin_catch_error

I am getting this error for a particular situation in our Kokkos library.
Unfortunately I wasn't able to replicate it without the whole library. But I
tracked it down to a situation that with a meaningless if condition added it
breaks, without the condition it compiles. 

This is the code:
#include<Kokkos_Core.hpp>

template< class Space >
struct NestedView {

  Kokkos::View<int*,Space> member ;

public:

  KOKKOS_INLINE_FUNCTION
  NestedView() : member()
    {}

  KOKKOS_INLINE_FUNCTION
  ~NestedView()
  {
    #ifdef BUG
    if(member.dimension_0() != 0) {
    }
    #endif
  }
};

Kokkos::View<NestedView<Kokkos::Cuda>*,Kokkos::CudaUVMSpace> foo() {
  return Kokkos::View<NestedView<Kokkos::Cuda>*,Kokkos::CudaUVMSpace>("A",10);
}

I attach a tar file with it. To build you need to clone Kokkos
(github.com/kokkos/kokkos) and checkout the clang-cuda branch. In the little
build line KOKKOS_PATH refers to the root path of your Kokkos clone. 

This is btw, the last issue we got with our non-experimental code in Kokkos.
