      Unintentional integer overflow

      The expression's value may not be what the programmer intended, because the expression is evaluated using a narrow (i.e. few bits) integer type. An integer overflow occurs, with the result converted to a wider integer type
      /test/format/config.c:585: OVERFLOW_BEFORE_WIDEN 121100 Potentially overflowing expression "workers * table_sumv(55U)" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned).
