> Found this while testing ARROW-13740. Using the nyc-taxi dataset:

> Interestingly, I can evaluate those filter expressions just fine, and it only seems to crash if both are provided. And I can count over the data with both:
> {code}
> ds %>%
> group_by(total_amount > 0, passenger_count > 0) %>%
> summarize(n=n()) %>%
> collect()
> # A tibble: 4 × 3
> `total_amount > 0` `passenger_count > 0` n
> <lgl> <lgl> <int>
> 1 FALSE FALSE 805
> 2 FALSE TRUE 368680
> 3 TRUE FALSE 5810556
> 4 TRUE TRUE 1541561340
