nvc++ is failing with:

NVC++-S-0000-Internal compiler error. unrecognized enum base type       6  (/home/coder/cccl/libcudacxx/test/libcudacxx/cuda/ccclrt/stream/stream_smoke.cu: 140)

if the line number is to be trusted, we are comparing two stream_ids here, which are defined as:

enum class stream_id : unsigned long long
{
};

Unfortunately, I cannot reproduce the failure in the same devcontainer locally :S

@dkolsen-pgi for your interest

Thanks for bringing the internal error to my attention. I'll get it fixed. (To reproduce the failure, the enum with an underlying type of long long or unsigned long long needs to be a member of an aggregate struct and an object of that struct type needs to be copied. I only know that by looking at the code; I never would have figured that out by trial and error.)
