[Mndiff-dev] [BUG] mnzip: exit status 1 with some some files

[Corey Hickey]

I don't know if this is a bug in compression or decompression, but 'mnzip
d' exits with status 1 even though the operation appears to work--the
output file is identical to the original.

You can get bzip2-ed source files here:

http://fatooh.org/files/tmp/mnzip/big.bz2
http://fatooh.org/files/tmp/mnzip/small.bz2

They're the first 4 MB and 1 MB of the linux 2.6.0 tar.

To reproduce, run a set of commands like this:

echo -----compressing-------
mnzip c0 small > out.mnz
echo exit status $?
echo ---------decompressing----------
mnzip d out.mnz > out
echo exit status $?

The "big" file has the same problem even with "c" instead of "c0".

I've posted logs:
