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:
  object passed to delete has wrong type:
  size of the allocated type:   1424 bytes;

Maybe a mismatch of lib and include..


Anyway, I'm on it, thanks a lot for the output,
