I hate to say this, but... I am giving up. I have a patch (see attach)
that compiles and does not crash, but badly breaks snow decoding. With
my current (mis)understanding of snow.c, I am not able to see why this
patch does not work (maybe there is just a small mistake, or maybe the
patch is completely wrong - this is why I am posting it: perhaps someone
can point out my error).
So, I have to better study the code (and the theory behind it), but this
will require much time (and I will not have much spare time in the next
weeks)... This is why I am giving up :(
