Another -dc device/host conflict with nvcc 10.1 + Thrust 1.9.4

[hwinkler]

Compiling this code with the -dc option to nvcc causes a device/host conflict:

#include <thrust/iterator/discard_iterator.h>
#include <thrust/device_vector.h>
#include <thrust/reduce.h>

void foo()
{
    auto probs = thrust::device_vector<float>(10, 0);
    auto fineProbs = thrust::device_vector<float>(10, 0);
    auto fineCells = thrust::device_vector<int32_t>(10, 0);
    thrust::reduce_by_key(fineCells.begin(),
                          fineCells.end(),
                          fineProbs.begin(),
                          thrust::make_discard_iterator(),
                          probs.begin());
}

Command line is

/usr/lib/cuda-10.1/bin/nvcc  -dc -std=c++11 --generate-code=arch=compute_60,code=sm_60  bug.cu

The error message is:

/usr/lib/cuda-10.1/bin/../targets/x86_64-linux/include/thrust/system/cuda/detail/reduce_by_key.h(1029): error:

I've attached this code and a makefile. #924 and #935 seem related but were against earlier versions.

This is a duplicate of #949; the fix is in flight, should land on github next week.

This should be fixed on master now; I don't yet know what CUDA Toolkit version the fix will land in.
