WavPack Hybrid broken on (Arch?) Linux, non lossless and heavily distorted Options

[skamp]

I tried to encode and decode several different WAV files from CD rips with WavPack (version 4.60.1) in hybrid mode, on Arch Linux, on two different machines (Intel Core i7 and Xeon, x86_64). I always got the same result: the files are heavily distorted (groups of samples repeating themselves), and obviously non lossless. See samples.

I ran the following commands:

CODE

wavpack -b400 -c -m hybrid.wav
wvunpack -m hybrid.wv

wvunpack outputs the following:

CODE

WVUNPACK  Hybrid Lossless Audio Decompressor  Linux Version 4.60.1

original md5:  e180f2ec2c4c65fd214bc6c4f70c7988        
unpacked md5:  2d5edeb0d3d7ba971282428b77fd41c6        
MD5 signatures should match, but do not!

I tried the win32 binary, which worked fine (lossless result). I don't have another Linux distro installed anywhere to see if this problem is distribution-specific. I also tried three different builds (including one built from source by myself), always with the same result.

That was irritating, entertaining, scary and plain hilarious at the same time. Thank you for linking that.
