This is likely from the return value of mclapply's FUN:
parallel:::sendMaster tries to serialize it, and fails.
serialize(integer(.Machine$integer.max / 4), NULL, TRUE)
do further data reduction before trying to return the results (probably
a parallel 'best practices' anyway). Neither traceback() nor
options(error=recover) deal gracefully with mclapply errors like this.
Hope that helps,
