The point I got to in looking through the code was that the vnc_read
function could close the fd and deallocate things before the second
FD_ISSET function... I assume that's what your patch fixes?
I can no longer make it crash with your patch applied, so I believe it
is fixed. Woohoo!
Could the same race condition occur in any other code paths? The other
crash I've seen appears to be similar but not related to the vnc
stuff...
Thanks!
