using `as_tsibble`, NAs appear to cause a C stack error

[njtierney]

When using as_tsibble, in this dataset with NA values, there appears to be an issue with converting it into a tsibble. Possibly related to #197

example_data <- tibble::tribble(
  ~year,                           ~unit_name, ~visitors,
   1939,             "Badlands National Park",    205100,
     NA,       "Honouliuli National Monument",        NA,
   1934, "Fort Donelson National Battlefield",     27127
  )

library(tsibble)
library(tidyr)

example_data %>% 
  drop_na() %>% 
  as_tsibble(key = unit_name,
             index = year)
#> # A tsibble: 2 x 3 [5Y]
#> # Key:       unit_name [2]
#>    year unit_name                          visitors
#>   <dbl> <chr>                                 <dbl>
#> 1  1939 Badlands National Park               205100
#> 2  1934 Fort Donelson National Battlefield    27127

But if using data that has NA values, I get this

> example_data %>% 
+   as_tsibble(key = unit_name,
+              index = year)
Error: C stack usage  7971536 is too close to the limit

Thanks. I'll look into this issue. But tsibble doesn't accept NA in the index column, and the expected error message is that index must not contain NA.

Thanks, @earowang !
