Serial SpMV fails on Kokkos-dev2 nightly

[lucbv]

The new serial specialization in Kokkos Kernels fails to compile in our nightly Jenkins build.
The error reported is related to a memset call that fails on Kokkos::complex see below:

03:26:59 /home/jenkins/slave/workspace/KokkosKernels_KokkosDev2_CUDA110_GCC92_cpp17/kokkos-kernels/src/sparse/impl/KokkosSparse_spmv_impl.hpp:344:7: error: ‘void* memset(void*, int, size_t)’ clearing an object of non-trivial type ‘using non_const_value_type = using non_const_value_type = using non_const_value_type = using non_const_value_type = std::remove_const<Kokkos::complex<double> >::type’ {aka ‘class Kokkos::complex<double>’}; use assignment or value-initialization instead [-Werror=class-memaccess]

should not be to annoying to fix : )

umm.... does this only happen on cuda gcc build ? Is it also reproduceable from just gcc serial build ? I am not sure why it complains bout the sizeof(object). It should work but the solution is easy. I will submit an PR for this soon.

This has now been fixed, thanks @kyungjoo-kim for working in this : )
