Or it seems, *no* core dump!

What are your OS and shell (R has not disabled it, but your OS 
probably has)?  The usual way to disable this is to set the limit on 
the coredumpsize to 0, and this seems a common default these days.

In csh, use e.g. limit coredumpsize 2000, in bash use e.g. ulimit -c 2000:
on my system the limits are in kbytes.
