I tried to reduce the offending portion as best I could to a
more-or-less minimal example (1136 bytes), which can be downloaded via:
wget https://www.dropbox.com/s/74rgxr5x2aalr99/badstring.R
then once in R,
> b <- parse(file = "~/badstring.R", keep.source = TRUE)
> d <- getParseData(b, includeText = FALSE)
> subset(d, line1 == 2L)
line1 col1 line2 col2 id parent token terminal
10 2 5 24 1 10 21 expr FALSE
> subset(d, parent == 10)
[1] line1 col1 line2 col2 id parent token
terminal
<0 rows> (or 0-length row.names)
here is my

note that while it says R version 3.0.2 above, I have seen the same
behaviour under version 3.1.2 as well.
