#include <avr/io.h>
#include <avr/pgmspace.h>
#include <string.h>

const char foo[] PROGMEM = "foo";
const char bar[] PROGMEM = "bar";

PGM_P  Langs[2] PROGMEM = {foo, bar};

int main(void)
{
  unsigned char i;
  char buf[2][5];
  
  //strcpy_P works fine with constant index
  strcpy_P(buf[0], Langs[0]);  //correctly copy 'foo'
  strcpy_P(buf[1], Langs[1]);  //correctly copy 'bar'
  
  //but strcpy_P copy char from wrong address if use variable indexing
  for (i=0; i<2; i++)
    strcpy_P(buf[i], Langs[i]);  //copy garbages!!!

  return 1;
}
