We have config parameter BugcheckAbort, making it possible not to try to continue server operation after bugcheck (which is hardly possible in most cases), but abort() at once, providing useful debug information - core file. But in many cases system is setup by default not to dump core at all. Users often have troubles, moreover setup using OS tools may differ for classic/super cases.

In order to avoid such problems, it's better to make firebird to as much as possible to create core file on BUGCHECK.
