traceback behavior differs from GNU R

[perNyfelt]

GNU R (3.6):

foo <- function(x) { print(1); bar(2) }
bar <- function(x) { x + a.variable.which.does.not.exist }
foo(2) # gives a strange error
[1] 1
Error in bar(2) : object 'a.variable.which.does.not.exist' not found
traceback()
2: bar(2) at #1
1: foo(2)

Renjin 3.5-beta76 (console)

foo <- function(x) { print(1); bar(2) }
bar <- function(x) { x + a.variable.which.does.not.exist }
foo(2) # gives a strange error
[1] 1
ERROR: object 'a.variable.which.does.not.exist' not found
at bar()
at foo()
