You say you're using CentOS. Is it possible for you test it on other systems and see if they're reproducible?

<br>
<br>It turns out that if you have an integer in a data table = 2^31-1 and you
<br>setkey on that variable, fail happens that sticks around after the failure
<br>and has some bizarre effects that don't look like they have anything to do
<br>with your index attempt or even the data table which you were trying to
<br>index, e.g., the error messages in the OP. Earlier in the day I had done
<br>such a setkey; even with the data table deleted and working on toy problems,
<br>as in the OP, these errors will occur.
<br>
<br>I can clean out all the variables etc., but the failure persists in the
<br>code, as some code appears to be overwritten when the attempt to index
<br>occurs. In RStudio the solution (other than the obvious "delete the
<br>observation with the value that causes the problem") is to restart R.
<br>
<br>More generally, the solution would be for the setkey function to check for
<br>values of 2^31-1 (or larger one assumes) on integer keys and fail
<br>gracefully.
