...and so you suspect that a k pointer, which is used by y(), is set
incorrectly? While this may be a reasonable guess, there might also be
something else wrong with your revision of the code - e.g., with the
loop logic. You may want to check the values of variables - e.g., see
if k is possibly too far away from the array start (beyond 768 entries).

All I can say is that you did something wrong, and that it's almost
certainly not specific to version 1.7.9 vs. 1.7.8. Maybe you did not
actually add that function in your 1.7.9-jumbo-5 tree, or maybe you
declared it static by mistake.

Given the partial info you've provided, I can only give you the hints
above, but not more.

Probably not.
