Hm. Why to use stack and fmemcpy()? Isn't better to access directly:
______________O\_/_________________________________\_/O______________
case 0x0a:
#define er (* MK_PTR (lregs, lr.DS, lr.DX))
CritErrCode = er.AX;
CritErrDev = MK_FP(er.ES, er.DI);
CritErrLocus = er.CH;
CritErrClass = er.BH;
CritErrAction = er.BL;
#undef er
CLEAR_CARRY_FLAG();
break;
_____________________________________________________________________
O/~\ /~\O
Or, if if by some reason doesn't wish to copy MK_PTR definition into stable
edition (why not?), _in given case_ you may do:
#define er (* (lregs FAR*) MK_FP (lr.DS, lr.DX))
