On the contrary, I'm currently implementing LTO in our project because it allows to uncover and fix the whole slew of latent problems related to ODR violations.

On the contrary, I'm currently implementing LTO in our project because it allows to uncover and fix the whole slew of latent problems related to ODR violations. At the same time I'm enabling UB sanitizers, so I'm confident that LTO will actually make our code more robust and reliable. The usefulness of LTO goes beyond better optimization, and it should not be ignored.
