In said commit, we silenced this warning by casting to uint64_t. The commit introducing this warning here (a93d81c84afa717b0a1a6947524d8d1fbfd6bbf5) anticipated it and so tried to address it the same way. However, it only did so in one of two places where this comparison occurs, and so we still need to fix up the other one.
