Probably you forget to increment value of "i" before return like i = i + 1;.

Why you are having char* argument as you are returning char*?

char* Test(char* str)
{
  static int i = 1;
  sprintf(str, "%d.", i++); // Now I remember to increment it.
  return str;
}
// ...
char sBuf[10] = {0};
int v = 0;
for( ; v < 3; v++) {
  printf(Test(sBuf));
  printf("\n");
