Compiler problems with far variables ?

Rabbit
1

While starting to work with Dynamic C 10.09 (the version shipping with RabbitCore 4200), I found two very strange compiler problem with far pointers, illustrated in the small program below.
I already found how to work around these by adding dummy lines of code or dummy variables, but I was wondering if these are known issues fixed in a later version of the compiler ?

/* Sample program to show some strange problems with far variables.

  • Problems seen with Dynamic C Version 10.09
    */

static const far char FAR_STR[] = “hello world”;

/*

  • Problem 1: defining a far char * in a structure just after an array cause
  •        it to be handled as a non-far pointer afterwards, in code

  •        checking as well as in code generation.

*/
struct {
char arr_a[2];
int x;
const far char *str_a;
char arr_b[2];
const far char *str_b;
} mystruct;

main()
{
mystruct.str_a = FAR_STR;
mystruct.str_b = FAR_STR; // this line is improperly handled
}

/*

  • Problem 2: returning a NULL pointer in a far char * function cause a
  •        compiler internal later in the compilation of the function.

*/
far char *rcGrowPtrOfs(int input)
{
far char *res;

if(input == 0) {
res = NULL;
return NULL; // this cause an internal error below / "return res;" works

}

return FAR_STR;
