For most embedded systems I know, core dumps are useful on the developer 
desk and in the testing lab. For analyzing field post-mortem (where it 
is feasible), use a custom fault signal hander in your app to catch the 
relevant information and save it.

If you're interested in a tutorial in doing this, I'm giving one at this 
year OLS. Or you can just check out the slides and example code here:

That's exactly what a custom fault signal handler does :-)
