It looks like the compressed chunk size in the chunk headers changed. MCServer seems to have uncompressed and re-compressed every pak file. The uncompressed size has stayed the same though. Every file is slightly large because of the compression size change. The denotch map converter must be compressing them in a format MCServer can read but doesn't like.
I'm using the -lz option when I compile using g++. It looks like it's using "/lib/libz.so.1.2.3.3" and it looks like you're using zlib-1.2.5
