I noticed fastr seems to be missing a warning on integer overflow.

For example:

$ graalvm-ce-java11-20.0.0/bin/R --quiet -e '2147483647L + 1L'
> 2147483647L + 1L
[1] NA

versus

$ R --quiet -e '2147483647L + 1L'
> 2147483647L + 1L
[1] NA
Warning message:
In 2147483647L + 1L : NAs produced by integer overflow
