Guys... something is definitely wrong with newSVpvf

Hi!

Have a look at this snippet of code:

SV* parse_hex (SV* name1,...) {
  Inline_Stack_Vars;
  int i,len;
  long long int ex, val;
  val=0;
  len=Inline_Stack_Items;

  char str[100];

  for(i=0;i<len ;i++) {
    ex=pow(256,i);
    val+=SvIV(Inline_Stack_Item(len-i-1))*ex;
    printf("ex=%lli, val=%lli, len=%i\n", ex, val,len);
  }
  return newSVpvf("%ill", val);
}

You would think it worked... but it doesn't! And why? Because the "%ill" 
conversion does NOT work correctly, it wants to write an int (or long int, 
dunno) instead, and it gives me back stupid numbers (however, when I write it 
to the console, i.e. printf, it gives me the right number). The solution is:


  char str[100];
  sprintf(str,"%lli",val);
  return newSVpvf("%s", str);

(this works 100% correctly)

which is funny, because it slows it down a LOT. I am absolutely sure this is a 
bug. Please correct it!
