mIRC 6.12 crash on WinXP with .NET - 04/11/03 05:17 PM
This happens everytime I connect to a random IRC server, with mIRC running a custom script. This only happened after I had to install the .NET framework because of VS.NET. I tried upgrading to .NET SP2 but no help.
I'm running Win XP with all the security patches. The mIRC error during crash is:
A chunk of disassembly (break point indended):
Note that this is reproducible down to the exact same memory addresses and assembly instuctions for every crash, but shouldn't be an exploit by someone as I connect to a random server and mIRC crashes within 2 minutes.
Appreciate any help, let me know any more info you need me to provide to trace this bug. Is anyone having the same problem ?
