Because abort() is correct for an assert() statement.

Yes abort() is causomg core dumping.
Why not use exit() with non-zero value ?

The function cdio_assert calls the standard C library routine abort();  see http://git.savannah.gnu.org/cgit/libcdio.git/tree/lib/driver/logging.c#n74 I believe that is what it should do. If you have arranged for abort() to cause a core dump, then in my view, that's the right thing to do here.

So why that test cannot just exit wit non-zero exit code?
Dumpig core is very strange way to confirm that everything is OK.
In my build env I'm monitoring and couting such things like core dumps.

I'm not sure this is a problem. The testassert program is supposed to fail and abort. The surrounding autoconf test suite then expects a failure.
