test/21_char_array fails on host=ppc about picoc HOT 15 CLOSED

it seems there is something wrong with pointers
i mean "*dest++ = *src++;" is not working as espected !


-------------------------------------------------------

test/21_char_array.c

int x = 'a';
char y = x;
char destarray[32];
char *a = "hello";

printf("%s\n", a);

int c;
int i;
c = *a;

char *b;
for (b = a; *b != 0; b++)
    printf("%c: %d\n", *b, *b);

char *dest = &destarray[0];
char *src = a;

i=0;
while (*src != 0)
      {
      *dest++ = *src++;
      }
*dest = 0;

printf("copied string is %s\n", destarray);

the following is NOT working if i declare "array[17]" as char, while it is 
working if
i declare as int


int array[17];
char *src = "0123456789abcdef";

int i;

printf("msg=%s\n", src);


array[0]='c';
array[1]='i';
array[2]='a';
array[3]='o';
array[4]=0;


i=0;
while (*src != 0)
      {
      printf("step %d:   ", i);
      printf("%c ", *src);
      array[i] = *src;
      printf("[%c] ", array[i]);
      src++;
      i++;
      printf("\n");
      }
array[i]=0;

printf("phase2\n");

i=0;
while (array[i])
      {
      printf("step %d:   ", i);
      printf("[%c] ", array[i]);
      i++;
      printf("\n");




if i declare as char i get the following output

msg=0123456789abcdef
step 0:   0 [] 
step 1:   1 [] 
step 2:   2 [] 
step 3:   3 [] 
step 4:   4 [] 
step 5:   5 [] 
step 6:   6       printf("[%c] ", array[i]);
                             ^
array2.c:22: this  is not an array

i tested picoC on x86 (little endian): test_21 has success !

we have the confirm: there is an endianless issue in the code !!!

Hi flamemanii, I believe I've fixed this problem. Can you please test the most 
recent
version and see if it's ok now?

Calling this one closed unless I hear otherwise

it is not fixed!!!! i can't see any progress: show me the code in where there 
is no
that issue!!!

Reopened this issue at flamemanii's request.

Hi flamemaniii, thanks for checking this for me.

What exact platform did you try this on? Which picoc version did you test?

machine: ppc-g4,g3,450 also mips-be, hppa-be: all bigendian machines fails !

tested:
* picoc-0.92.tar.bz2
* svn checkout http://picoc.googlecode.com/svn/trunk/ picoc-read-only, Checked 
out
revision 359

is there an other version/branch?

Thanks. I don't have access to a big endian machine at the moment but I'll see 
what I
can do to find the problem.

I finally got access to a G4 to look into this bug.

Fixed in revision #371

flamemaniii, please let me know if you still have any problems.

i manually grabbed your #371 diff and manually patched expression.c of the last
public release picoc-0.93

well, on my ppc7410 the "Test: 21_char_array" has now success, but it seams 
there is
an issue with fixed point math
