If you looked at the commit log, you'd see how I tested this:
    touch defconfig
    for(( i=0; i<10000; i++ )); do
        KCONFIG_ALLCONFIG=$(pwd)/defconfig make randconfig >/dev/null 2>&1
        make silentoldconfig </dev/null >/dev/null 2>&1 || break
    done

That is, 10 thousands random configurations, and none did exhibit the
problem. :-(

Which really means we need a comprehensive test-suite to kconfig.

I would not call delving into the kconfig code 'fun'. ;-)
