[sdcc-devel] More on paramBytes bug.

Ok, I've traced it down but I dont understand it.  The flow is:

* geniCodeCall (actually sets parmBytes) from the result of:
* geniCodeParms which generates a 'stack' size from summing the
  size of all stack pushed parms.  This is from the result of:
* ...many calls to getSize()

getSize is where things break.  getSize is basically:

if IS_SPEC(p)   (is a char, short, int, long...)
   return sizeof(p);
else is a pointer to something.
   return sizeof(POINTER in appropriate space)

The problem is that its dereferencing the paramater down to a char, so
IS_SPEC is true, and sizeof(char) is returned instead of sizeof(char *)

Thats where I get lost.  I cant find where the 'class' is actually set,
and the diffs against two weeks ago look fine to my untrained eye.

Yeah.  I'll keep hunting.  My notes are in doc/random-notes.txt.
