Pointer Trouble...

[Jacob Christ 0]

This does not work:

   #define s8 char
  #define us8 unsigned char
  s8 i;
  for(i = 0; i < sizeof(data); i++) {
  ((us8 *)&data)[i] = 0;
  }

 

But this does:

 

   #define s8 char
  #define us8 unsigned char
  s8 i;
  us8 *p1;
  p1 = (us8 *)&data;
  for(i = 0; i < sizeof(data); i++) {
  p1[i] = 0;
  }

Thanks for reportng. This is a known problem. Compiler will not apply array element operation [] to an expression that doesn't evaluate to a variable. A workaround is as you described by introducing a temporary variable that will replace the expression and applying array element operation to this variable.

Fixed. Fix will be available in the next release.
