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! P.S. Sorry, i mispelled my kernel version, it is 2.4.33.3, not 2.6.17.13. |

Confirmed with your example (it doesn't happen for every nonexisting word btw, it's something with end-of-array or something). EDIT: Sorry you already said that :P. Anyway 'w' is near the end of the alphabet, that's probably it. In either case, we'll look into it, thanks :) |

As syzop stated, it was indeed just an "end of the array" issue. Fixed in .2272 (devel branch). |
