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.
