[389-users] Segfault

[Edward Z. Yang]

After manually attaching GDB, we caught a segfault on one of the dirsrvs.  The
server's name is old-faithful.  Here's the backtrace (with one set of debugging
info missing; I can grab that and reload the core dump if you want me to.)
File a bug, or do you think it's an upstream bug?  The core dump probably
contains sensitive info, so let us know if there are specific things you
want us to do with it.
