An internal error occurred

[rbotafogo]

Executing the following code in fastR console:

library('dplyr')

df1 = data.frame(x = 1:3)
print(df1)

form = quo(y <- a + x)
print(form)

mutate(df1, !!form)

returns:

An internal error occurred: "java.lang.ArrayIndexOutOfBoundsException: -1" fastr_errors_pid24394.log

Hello Rodrigo,

thank you for the report. On the current master I am getting a different error:

> mutate(df1, !!form)
Error in mutate_impl(.data, dots) :
  Evaluation error: object 'a' not found.
In addition: Warning message:
In mutate_impl(.data, dots) :
  mismatched protect/unprotect (unprotect with empty protect stack)

in any case, we'll investigate and fix this.

Hi Stepan,

The error you are getting is what I was expecting. So, maybe this will be in RC15.

Thanks

Great, in that case please reopen this issue if it is not gone in RC15.
