It's impossible to tell what your issue may be with the information provided. It looks like you're using something that hasn't been properly initialized. Closing this for now, feel free to supply more information and we can try to help.

I'm so sorry! Perhaps, the reason is I have tried to resolve the source1 dem file!
I have another question : What's the mean of the struct CDemoStringTables in the struct CDemoFullPacket ?
When I parser a dem file , most of the parses show that they belong to the struct CDemoPacket !
