--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
But this is not the result of sanitizing but is -Wformat-truncation diagnostic
which of course depends on the IL which _is_ influenced by sanitizing.

I think you misread the documentation.  Runtime sanitizer diagnostics are
not supposed to be affected by optimization level.
