As long as you have "ulimit -c" set high enough, it should dump the core
on Linux (it certainly works fine with Apache 2.0).  Depending upon 
your shell, you can specify "ulimit -c 100m" which will allow 100MB 
core files to be created.  Most likely, it'll dump the cores in your
apache-1.3 directory.  

You know that seems to be an obvious omission from the debugging
page.  Hmph.  

HTH.  -- justin
