Comment (by H2Swine):

 I wonder whether it is the ALS reference encoder that is buggy about
 certain WAVE files and then produces an invalid encode? Indeed it has just
 come up that yes it doesn't handle WAVE well:
 https://hydrogenaud.io/index.php/topic,109239.msg1045191.html#msg1045191

 So that might be the reason that this 44100/16 stereo file doesn't work:
 https://www.sendspace.com/file/qg9j3u contains both the ALS encode and an
 original - as .tak to save space.
