I haven't tried to analyze it. If you notice that top dumps core with a FP exception, wait a while (couple of minutes) and it should be gone again. As for trying to get a backtrace: I noticed that when there's no debug information available or when no debug information had to be created by the compiler, the debugger gets confused. This is due to the kludgy way the debugger scans function prologues to get return addresses and previous stack pointers and the like (at least that's what I think is going wrong). I'm working on that... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
