The crash occurs when wcsncpy is called with the third argument negative inside the function CHudSayText::SayTextPrint.

The bug still works on last beta. To verify this, you need to connect to HLTV server and send a few labels to chat, for example say #spec_help_text #spec_help_text

Oh, I'm sorry, I completely misinterpreted this report. I thought it was reporting that the third parameter to SayTextPrint (clientIndex) was negative and that was causing a crash (which I found it would if it is negative, so that is what I fixed). I should have the actual issue here fixed in the next beta.
