[Zlib-devel] known bugs in distance-checking code?

If I understood Mark's comment about calloc() correctly, I believe
it's because they assume the (wrapped) window is initialized with
zeros (i.e., they're basically assuming a preset dictionary containing
strings of up to 32,768 NULs), and that assumption is completely valid
for the old decoder.
