Thanks!

Here we go.

Thanks. Looking at it I am not sure why libopenblas.so.0 get loaded on
your system as it is not a(n indirect) dependency of mpv. Do you
remember if you might have manually installed some of the libraries
depending on it? But maybe that's unrelated to the issue.

I don't think so, or at least, i don't remember.
The only relevant installed package is i   libopenblas0-pthread

Please also check that libresolv.so.2 is not corrupted:
$ md5sum /lib/x86_64-linux-gnu/libresolv.so.2
beee3cba5ce568d2bf5189acf7d5c56a  /lib/x86_64-linux-gnu/libresolv.so.2

$ md5sum /lib/x86_64-linux-gnu/libresolv.so.2 beee3cba5ce568d2bf5189acf7d5c56a /lib/x86_64-linux-gnu/libresolv.so.2

No problem here.

Finally, if all that looks correct, we might need to look at a full
debug ouput of ld.so:

 LD_DEBUG=all /usr/bin/mpv

Well, the log is 480MB :)

However, it finishes with:
297755: binding file /lib/x86_64-linux-gnu/libflite_cmulex.so.1 [0] to /lib/x86_64-linux-gnu/libflite.so.1 [0]: normal symbol `item_prepend'
297755:
297755: relocation processing: /lib/x86_64-linux-gnu/libflite_usenglish.so.1

I downloaded libflite1_2.2-7_amd64.deb, and indeed, my /lib/x86_64-linux-gnu/libflite_usenglish.so.1 had not the same MD5 than the one from the package. I replace mine by the one coming from the package, and the bug is resolved.

Thanks a lot!

All the best,
Fabien
