#define VAL_COUNT_MAX   4
#define VAL_WORDS 6

const int VALS[] PROGMEM = { 
  0x20DF,  0x08F7, 0x8877, 0x48B7, 0xC837, 0x28D7
  ,0x4040,  0x00FF, 0x807F, 0x40BF, 0xC03F, 0x20DF
  ,0x0101,  0x7887, 0xC03F, 0xC837, 0xD827, 0x20DF
  
  ,0x807F,  0x708F, 0x807F, 0x40BF, 0x609F, 0x20DF        //      Please Comment it when Use VAL_COUNT_MAX = 3    !!!     <<<<<<<<<
};

first, sorry for bad english,
Environment: Arduino Uno

BUG is in calculating Used Space of flash memory (32k)

  1. PROGMEM used for int array.

  2. Array is 4 Groups of (6 ints).

3)VAL_COUNT_MAX is the groups count.

  1. using this data in the program.

  2. when set VAL_COUNT_MAX = 4 and use the all values in array above Sketch uses 1392 bytes.

  3. when set VAL_COUNT_MAX = 3 and use only 3 rows in the array Sketch uses 1426 bytes !!!

  4. in 6 i expect Sketch uses 1392-12 bytes why it uses 1426 bytes?? is it BUG ??

thanks for support.
