How to Reproduce

Compile with UBSan on G++13 the following code
thrust::async::reduce(thrust::cuda::par.on(stm), d_in, d_in + n, double(0), thrust::plus<double>()).get()

Expected behavior

No error during runtime.

Thx for reporting this! We should have a quick look whether the bug comes from the thrust::async::reduce implementation, since it is deprecated and will be removed at the next major release.

I could reproduce the issue with nvcc 12.2 (newer versions fail to execute the compiled program) https://godbolt.org/z/haGaevTjc. It's still present in CCCL main.

However, thrust::reduce does not have the problem. Given thrust::async::reduce is scheduled for removal, I will close this bug as "not planned". Thx for reporting!
