dplyr crash with arrange on R 3.3.0

Any idea why this might be happening?

I'll use a reprex from Hadley's R for Data Science book, Exercise 4.4.1, 1: put NA at the top of the flights dataframe with `arrange()`.

```
library(dplyr)
library(nycflights13)
```

Any of these causes a crash:

```
arrange(flights, is.na(flights))
arrange(flights, desc=is.na(flights))
```

But not this:

```
arrange(flights, is.na(arr_delay))
```
