Hi!
I encountered crashes of my R session in this specific misuse of dplyr. I was unable to break it down any further:

MWE:

library(dplyr)

a <- data.frame(x= 1)
b <- data.frame(y = character(), # runs fine with integer()
                stringsAsFactors = F)

g <- function(y){1} # 1 or y
f <- function() { b %>% rowwise() %>% mutate(z = g(y))}
try(f())
print("f ran fine (with eror)")
try(a %>% mutate(b = f()))
print("f ran fine (with eror) within mutate")
try(a %>% rowwise() %>% mutate(b = f()))
print("f ran fine (with eror) within rowise mutate")

Output:

Error in mutate_impl(.data, dots) : 
  Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'pairlist'
f ran fine (with eror)
Error : Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'pairlist'
f ran fine (with eror) within mutate
<RSession crash>

Session info:

R version 3.2.1 (2015-06-18)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 8 x64 (build 9200)
other attached packages:
[1] dplyr_0.4.2

all the best and much fun to the one taking it on,
Jan

👍 Thanks!

Renders the previous test about #1300 irrelevant, so I removed it.
