Hi Buland, Thanks very much for your answer! After installing the right debuginfo package, now crash works! BTW, if possible, could you spare a little time to explain other confusion: it seems that I don't select whether "debug" version or not during install RHEL 7, why does it install the "debug" version for me? Thanks!
