Subject Core dump with 1.2b9-dev, gdb trace
Date Sat, 12 Apr 1997 19:21:48 GMT

This with a version current as of April 8th, 1am.  Looks like the call to
get_remote_host returned something Apache didn't like - I am using bind 8.1 and
its resolver library.  

Program terminated with signal 6, Abort trap.

It appears to be a pretty transient failure, as I have hits from 207.137.164.69
at the right time and place, save for a single

  www.apache.org|207.137.164.69|-|-|200|1997/04/11-16:48:02|-|-|-|-|-|-

Anyways, just FYI.  I know we don't check the return of many system calls and
that this is a larger problem.
