Goof Info
Submitted by Bitbreaker on 14 April 2013
The packer produces wrong output when a file contains a too long literal run that needs to be split up. Then the order of the multiple literal runs is wrong due to the optimal_parsing function runing top->bottom. That means, that in case of splitting, first the literal with a length of (runlength % 256) is output and then literals with maximum runlength. Correct however would be to first have 1/many literal runs with maximum runlength + one with the remaining bytes. Fixed that in lz.c and will release it after more testing. But so far, all broken files pack fine now.
Okay, more bugs to be removed. The packer splits up too long literals into 257 byte chunks, just one too much. But even with 256 byte chunks the depacker (6502) will fail, as it the page crossing check fails with ann add of zero. Thus the needed type bit is missed.
