-Description: Move tests that trigger -Warray-bounds to separate compilation unit
- GCC 10 is now smart enough to detect violation of array boundaries that tests
- are actually tested. Along with -Werror this led to tests failure, so I move
- such tests to another compilation unit to have the warning deactivated for
- only these tests.
