I've created a <a href="https://drive.google.com/file/d/0B8vFUUth7NpvRFI0MmI2bVJNNEU/view?usp=sharing">small OS X example project</a> that reproduces the issue. (I've run into the size limit for emails on this list so I've put it on Google Drive.) The program just initializes a libFLAC++ stream decoder for a given file and attempts to seek to frame 0. All I've done to the libFLAC code is add a few print statements that make it clear where the failure is happening. The file 'fails.flac' demonstrates the issue. The file 'succeeds.flac' is in the same format but can seek successfully to 0.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I'm running Xcode 8.1 on OS X 10.11.6.

<font face="Courier New, Courier, monospace">I was wondering when it
would be useful to compress very short audio files. The answer may
be when there are lots of files, for instance in the case of sound
fonts, or a large collection of transients. Probably it would be
better to compress the whole collection as a single large file
obtained by juxtaposing the short clips, with cues or marks to
separate the original files. May be this allows a more efficient
way to deal with headers.<span class="m_-4950834886851007258HOEnZb"><font color="#888888"><br>

<pre>I was hoping to tackle this last weekend but I didn't manage to find
time. A small test case would be very useful indeed.
