Sorry, it did not occur to me to preserve the core file: If it was in 
fact dumped at all, I guess it got cleaned out automatically at next 
boot - in any case it there's no core file by now :-(

I have no suggestions how to continue from here - if you don't either 
then I guess there's no other option than filing it as a mystery.
