Describe the bug

This test has started failing after this commit: c156e90

#include <execution>
#include <algorithm>
#include <vector>

template <typename T>
struct LocalWrapper
{
    explicit LocalWrapper(std::size_t k) : my_val(k) {}

  private:
    T my_val;
};

int32_t
main()
{
    typedef LocalWrapper<double> T;
    auto pred = [](const T& x) { return true; };
    const std::size_t max_n = 1000000;
    std::vector<T> in;
    in.reserve(max_n);
    const bool actual = std::is_partitioned(std::execution::par_unseq, in.begin(), in.begin() + 100, pred);
    return 0;
}

it fails with:

cub/agent/agent_find.cuh", line 106: error: no default constructor exists for class "LocalWrapper<TestUtils::float64_t>" (aka "LocalWrapper<double>")
      InputT input_items[items_per_thread];
             ^

How to Reproduce

nvc++ -stdpar --c++17   test_is_partitioned.cpp;

Expected behavior

Test should compile fine after the fix.
