--- Comment #5 from yhf8377 <general at yhf8377 dot me> --- Thank you Thomas for the detailed information and links to the references. I guess I will need to move this bug report into our own bug tracker. :-) This is indeed a bug in our code as we had incorrect assumptions on how `std::reduce()` and `std::execution::seq` work. Thanks again!
