Source code is

         printf ("returned value is %O\n", _gst_last_returned_value);

Plenty of duplicates in the same file.

The warnings are annoying but they are misleading. Our "printf" comes
from the GNU snprintfv library which has a function to register
extensions (e.g. %O) to it. I think the documentation from GNU libc
applies here as well:
https://www.gnu.org/software/libc/manual/html_node/Printf-Extension-Exam....

Maybe you can see if we can teach the compiler that %O is valid and
expects an OOP?
