[datatable-help] error in rbindlist

[Farrel Buchinsky]

I am doing something really simple but getting an error I do not know how
to troubleshoot.

l = list(specimens, specs.post.crash)
rbindlist(l, fill = TRUE)

specimens has about 5 columns and specs.post.crash has about 29.

I get this error. I cannot find anyone else with this problem. I cannot
share my actual data.table since it has private information.

Error in if (any(neg)) res[neg] = paste("-", res[neg], sep = "") :
  missing value where TRUE/FALSE needed

Interested in the off-the-top-of-your-head suggestions of where to
troubleshoot.
Using {R package version 1.9.5}
