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?

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?

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

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
