===================  STOP HERE ======================

Copy the parts between the START HERE and STOP HERE marker
and report it on http://bugs.unrealircd.org/

But before you do, note the following:
1. We do not support modifications of any unrealircd code
   (except for config.h changes).
2. If you are using 3rd party modules we might request you
   to run without them and verify you still crash. This is
   to eleminate any loss of time due to bugs made by others
3. Always use the latest UnrealIRCd version, we fix (crash)bugs
   all the time so your bug might as well be fixed already.

Thanks!
