| They're just initialized to some unspecified value and cause almost-as-hard-to-diagnose faults. |

| ▲ | bluGill 7 months ago | parent [-] | | the unspecified value is supposed to be something really obviously wrong (in particular sanitizers will look for it.) and so be easier to diagnose with tools. Unlike 0 which is really hard to diagnose because often it is the right value and so when it isn't you won't realize what you did wrong. |
