Also, here's how I launched valgrind. If more detailed options are
necessary please let me know.
$ valgrind --leak-check=yes ./src/.libs/pulseaudio ...
Well, that differs from the way I tried that:
valgrind --trace-children=yes ./src/pulseaudio
The difference is because our intentions were different: you were focusing
on finding memory leaks, while I was searching for uninitialized variables
and use-after-free errors. And, I was trying to make sure that the
just-compiled libraries are used, and the libtool-generated bash wrapper
knows best how to do that.
Of course, we can combine our flags, and replace --leak-check=yes with
--leak-check=full.
You could also use this to make sure the libs are picked up from the
build directory:
libtool --mode=execute valgrind --leak-check=full --trace-children=yes
./src/pulseaudio
Thanks for the tip.
Anyway, here is what I get with the portable version of libressl
(installed into a separate prefix in order to avoid conflicts with the
system-installed openssl, and added to PKG_CONFIG_PATH).

On starting playback with mpv: nothing! At this point, I'd seriously
suggest, as a future project (after merging), evaluation of alternatives
to OpenSSL as an RSA crypto engine in the RAOP sink.
