I'm not sure how to enforce "don't enable this unless you're developing the Overflow Behavior Types" with current Kconfig, given the randconfig gap... I have some memory of Arnd doing something special with his randconfigs to avoid these kinds of things, but I can't find it now.
The main thing I do on the randconfig builds to avoid obscure issues
is to force CONFIG_COMPILE_TEST=y, but that only works for build
testing, not actually running it.
