[Rcpp-devel] bug with DatetimeVector ?

[stat quant]

Hello list, I might have found a bug, would you mind checking it too?

In R:

library("Rcpp")
sourceCpp("rcpp.cpp")
df = data.frame(x=c(1L,NA,2L),
dt=as.POSIXct(c(1L,NA,2L),origin='1970-01-01'))

df
   x                  dt
1  1 1970-01-01 00:00:01
2 NA                <NA>
3  2 1970-01-01 00:00:02

In C++

//[[Rcpp::export]]
void bug(DataFrame df){
    DatetimeVector dt = df["dt"];
}

Executing bug(df) in R crashes the R session on my box
