I have what should be a fairly plain WAV file -- it's 44.1khz, 16-bit,
produced by the "flac" command-line tool, but when I run ffprobe on it, it
fails:

This seems very similar to ticket #2810 but I assume that a release as
recent as 2.2.4 would include that fix. Could it be a regression?
I can't upload the full affected WAV, but I'll upload a 10 second snippet
from the start that produces the same error.
Thanks
