calc: C-style arbitrary precision system

In opcodes.c:

S_FUNC void
o_printresult(void)
{
VALUE *vp;

vp = stack;
if (vp->v_type == V_ADDR)
vp = vp->v_addr;
if (vp == NULL) return; /* <<<<<< fix here */
if (vp->v_type != V_NULL) {
if (conf->tab_ok)
math_chr('\t');
printvalue(vp, PRINT_UNAMBIG);
math_chr('\n');
math_flush();
}
freevalue(stack--);
}


In value.c:

void
copyvalue(VALUE *oldvp, VALUE *newvp)
{
if (oldvp == NULL) return; * <<<<<< fix here */
newvp->v_type = oldvp->v_type;
if (oldvp->v_type >= 0) {
switch (oldvp->v_type) {


Now the following, instead of crashing:

rpnstack = list()

followed by:

rpnstack[0]

returns:

Index out of bounds for list
Misaligned stack


which is reasonable, although not necessarily
the way it should be fixed, I don't really
know the code well enough.
