vctrs::vec_group_loc returns unxected result for int64 vector

[andreymalakhov]

vctrs::vec_group_loc behaves strangely with int64 values, for example for below 10 different ints, it groups it in 3 categories, while if the same vector is transformed to character, it separates to 10 different groups.

What version of vctrs are you using? It works as expected for me with CRAN vctrs. Also note that the R parser can't parse double values as big as your input (look at the 2nd value here for example, it is different from the input value).

Ah, thank you for pointing out to the version, indeed with the latest 0.6.5 from CRAN it works, as expected. Thank you for pointing it out.
