Run file(1) on the .wav file and send the output.  Particularly, what are the
sampling rates of the input files?

I ran a simple test to try to reproduce your problem, and I happened to grab
one wav file which had a sampling rate of 4660 and was able to reproduce
your problem.  flac works fine on the other files, which have more normal
sampling rates (8000, 16000, 32000, 44100).  If I use sox to convert the
sampling rate of the problematic file, flac works on the result.

In my case, the files I tested were:

RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz (works)
RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 4660 Hz (fails)
RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 8000 Hz (works)

The third is just a sox-converted version of the second, so this definitely
seems to be related to the sampling rate.
