Hi Mark,
of course that's on me to fix, and yes - the string handling is really
a bit tricky. At some point I had introduced av_strdup() everywhere after I
realized that it's too hard to track which strings might stem from literals
and which are not, so it's very plausible that I missed some cleanup.
I've enabled ASAN just an hour ago and currently digging into other errors
it is showing like that one:
==11668==ERROR: AddressSanitizer: new-delete-type-mismatch on 0x122d130b6580 in
thread T0:

Maybe a mismatch of lib and include..
Anyway, I'm on it, thanks a lot for the output,
