[datatable-help] R-devel breaks data.table

[Kevin Ushey]

Hi guys,

See the commit here:

https://github.com/wch/r-source/commit/d0aece456bae5377245eb550a7434ba517be12fe

Now if I run the following code, I see an error:

library(data.table)

DT <- data.table(x=1, y=2, z=3)
DT[, k := 4]

Error in `[.data.table`(DT, , `:=`(k, 4)) :
  attempt to set index 3/3 in SET_STRING_ELT

Is this R-devel being overly picky about data.table's overallocation,
or is this a bug in data.table?

This is with data.table 1.8.11 from R-forge (version from yesterday).
