Get cudaErrorIllegalAddress when running ctc decoder on H100

[Ray-Leung]

🐛 Describe the bug

I am getting this error when running the sample code form pytorch https://pytorch.org/audio/2.2.0/tutorials/asr_inference_with_cuda_ctc_decoder_tutorial.html?highlight=ctc
But everything is okay when running on both 4090/3090 machine.
What kind of issue do I run into on the H100 machine, but not on the 4090/3090?

Error Message

> File /__w/audio/audio/pytorch/audio/src/libtorchaudio/cuctc/src/ctc_prefix_decoder_kernel_v2.cu Line 880 cudaMemcpyAsync( select_seq_lens.data(), log_prob_struct->select_seq_lens, sizeof(int) * bxs, cudaMemcpyDeviceToHost, stream) returned cudaErrorIllegalAddress.
