it seems like commit a576954f9b96d2777d8cce09be31eb3f62e0e882 has introduced a new bug

int fromBase8(const char* s, const char* end) {
    int result = 0;
    while (*s && s != end) {
-        if (*s <= '0' && *s >= '7')
+        if (*s <= '0' || *s >= '7')
            return 0;
        result *= 8;
        result += *s - '0';
        ++s;
    }
    return result;
}

int fromBase8(const char* s, const char* end) {
    int result = 0;
    while (*s && s != end) {
        if (*s < '0' || *s > '7')  /// HERE, NO EUQAL
            return 0;
        result *= 8;
        result += *s - '0';
        ++s;
    }
    return result;
}
