Error: serialization is too large to store in a raw vector

Dear all,
I have quite large code (with lapply and mclapply)
and I am getting the following error.

Error: serialization is too large to store in a raw vector

Is it possible to ask from R to extend the Error messages with more details?
I would like to see where this problem exists.

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,

Martin
