It's not easy, but the general idea is to do it in gdb, possibly with a 
nicer front end (I use Insight).  I wrote up instructions on doing this 
in Windows a few years ago.  I think they still work; if you try this 
and notice anything in my instructions that is out of date, please let 
me know.

The instructions are on 
http://www.stats.uwo.ca/faculty/murdoch/software/debuggingR/, in the 
page "Using gdb to debug C or Fortran code
