SYMPTOMS
========
If the code below assembled with Microsoft Macro Assembler (MASM) version 5.1,
it produces the following error:
Warning A4057: illegal size for operand
This warning is falsely generated and does not occur with MASM version 5.1a.
The variable arg1, shown in the code below, is a local variable that is defined
as a double word. The warning occurs when arg1 is used as a WORD PTR. This is
acceptable and should not be flagged.
STATUS
======
Microsoft has confirmed this to be a problem in MASM version 5.1. This problem
was corrected in version 5.1a.
