All of us know that audiofile is in a particular situation.
Years ago I (and probably someone else too) reported a lot of security holes, that were partially fixed upstream.
Now seems that we are apply a debian patchset to fix reported vulnerabilities, so our version is a bit different from 'pure upstream' considering also that last commit upstream was 7 years ago.

So this issue occurs in the 0.3.6-r5 version that we have in the main tree and I did not test further version (like master, considering what said above)

I know that you know, but for completeness I should say that you can see the same error when you compile the package with -fsanitize=address, or if you don't like it, maybe valgrind will do the same or playing a bit with gdb should show up to the same conclusion.

I'm attaching the full log and the testcase.

The command to reproduce is:

Maybe you could work on a patch? Or test with the Debian fork? Or report to Debian?
