--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The manual says:

The effectiveness of some warnings depends on optimizations also being enabled.
For example -Wsuggest-final-types is more effective with link-time optimization
and -Wmaybe-uninitialized does not warn at all unless optimization is enabled.
