I was thinking an extension might be defining a stream and > setting this. i think the problematic scenario would be an extension that was previously compiled with (and allocated/initialized an instance of) the old smaller struct, which then passed said struct to a function from the newer core version, which would expect that it was a the new (larger) struct, and attempt to access memory outside the bound of the older struct. but i'm not familiar enough with the code in question to know how this struct used and passed around between extensions and the core. sean
