In the build script /usr/bin/build there exist

```
setmemorylimit() {
    if test -n "$VM_ROOT" -o -n "$RUNNING_IN_VM" ; then
        return
    fi
    local mem
    local limit
    while read mem; do
        case "$mem" in
            MemTotal:*)
                set -- $mem
                eval "limit=\$(($2/3*2))"
            ;;
            SwapTotal:*)
                set -- $mem
                eval "limit=\$(($2/3*2+$limit))"
            ;;
        esac
    done < <(cat /proc/meminfo) # cat for proc stuff

    ulimit -v $limit
    echo "Memory limit set to ${limit}KB"
}
```

which is called lateron without any option check and this leads to

```
