Buffer overrun detected!

[lorun]

Hello,

I have setup a server runing under ubuntu 8.10 and compiled with gcc-4.2, everythings look to work well except some characters experiencing a Buffer overrun after the char selection screen.

The zone load up correctly but the char ll never enter the zone and the client ll crash...

I have no idea on how to solve that.
Tried to movechar to an other zone.
delete char.
delete account. (after that the client can sometimes login).

The things i dont understand is some can login and never experience the problem.

I cant change the os to debian and compile with gcc-3.6 cause my server hosting websites and it would take to much time to move all the websites.

Have you experienced this problem ?
Do you have any idea on how to solve it ?.

Client 'Toto' was destroyed before reaching the connected state:
We successfully sent player info and spawns, waiting for client to request new zone.

This is the only info i can find in the logs.

Thx for your help.
