Hi,

I am just trying a bit around using assembler, and run into problems.

just multiplying integers a and b to res as result. this works fine.
 int a = 2,b = 3,res;
 for (int i=0;i<100;i++) {
  __asm{
   mov eax, a
   mov ecx, b
   mul ecx
   mov res, eax
  } }

then why does this not work? that is, it works fine for 4 iterations or so, 
then it comes up with illegal flaoting point operation. even if I only have 
"fld d_a" it throws the error.
 double d_a = 1.1, d_b = 1.2, d_res;
 for (int i=0;i<100;i++) {
  __asm{
   fld d_a
   fmul d_b
   fst d_res
  } }
