Dear Maintainer,

I was attempting to process genre information off of my music files, which
consist of a collection of .mp3 and .m4a files. While processing these files,
both in python with pymediainfo and later with my own C++ program using
libmediainfo directly, the library would crash. Here is a backtrace:

[New LWP 502901]

FYI I tried building against the upstream source and the issue appears to be
fixed there.

Hi,

I can't seem to reproduce it with my local files. Could you upload some
sample affected files for me to check please?

Also, if you're able to, could you see if the version in testing
(25.10+dfsg-1) works for you?

I found out that it was not any one file, it manifested by checking hundreds of
files, so perhaps some kind of resource leak.

I'll try it.
