Public bug reported:
- When running 'sndfile-info' program from 'sndfile-programs' package, the
program crashed while trying to write on invalid memory address. The crash
point is wav_w64_read_fmt_chunk() function of libsndfile.so, so the bug seems
to reside in 'libsndfile' package.
- 'sndfile-play' program from 'sndfile-programs' package also crashes with the
same input.
