Does this involve your own compiled code?

If so, run R under a debugger (e.g. R -d gdb) when you will get more 
information.  (You may also be able to get a core dump from option 1 and 
look at that in a debugger, but what happens is OS-dependent, including 
system settings in the OS.)

If not, it is likely to be a MacOS-specific problem, so please send a 
reproducible example to the R-sig-mac list.
