Broken with libFLAC < 1.4.0 ("internal psf_fseek() failed")

Some versions of the SoundFile package on PyPI, including the latest version (0.12.1), appear to be broken. It appears that something is wrong with the precompiled "libsndfile_x86_64.so". I have no idea about other platforms. I don't know if this is actually a bug in libFLAC, or in libsndfile, or in SoundFile, or a bug in how libFLAC/libsndfile was compiled.

The latest version in the libsndfile-binaries repo is possibly fixed, but there hasn't been a new release of SoundFile for a while.

Here is an example file, gzipped and base64ed:

I think this is a valid FLAC file, though I'm not sure. Running python3 -c 'import soundfile; soundfile.SoundFile("example.dat").read(78419)' should succeed.

• With python3-soundfile (and libsndfile) from Debian bookworm, it works.
• With libsndfile_x86_64.so from commit f5311e9 (md5 = 8e42bd39f38254cf9a5c8ad1bc975faa), it fails.
• With libsndfile_x86_64.so from commit 1ddbbd5 (md5 = 44c0cbf5b8f2a96d309d3e648718bdec), it fails.
• With libsndfile_x86_64.so from commit f1655ba (md5 = 1bd1cc5a1b3724c97ea26d007110e5f1), it works.
• With libsndfile_x86_64.so from commit 42c638d (md5 = 243f680f7a517539fe867731fc5fd5d0), it works.

Start by reproducing the failure with the embedded example.dat data and the documented SoundFile command, comparing the listed libsndfile_x86_64.so commits and Debian's libsndfile. Determine whether the defect is in libFLAC, libsndfile, SoundFile packaging, or compilation; done means the example FLAC reads successfully with the released package.
