Sorry to have bothered everyone. I think that I've figured out what was going on. The program in question is started (as root) via /etc/rc5.d script. One of the first things it does is to setuid(2) to a non-root user for security, in case there would be an exploitable bug in the code. Well, it seems that setuid(2) will prevent the process from subsequently dumping core. I suppose that's a security precaution, too. Of course, it does not bother to say what is required to explicitly *un-do* that. I mean, I *want* to be able to make the program dump core. There has to be a way to do it, otherwise no non-root process would be able to dump core. Does it require an exec()? Or, is there another call that can be made that would be good enough to turn core dumping back on? Thanks!
