Q120064: BUG: Error A2005 Generated Due to Conflict with Global Label

Article: Q120064
Product(s): Microsoft Macro Assembler
Version(s): 6.1,6.11
Operating System(s): 
Keyword(s): 
Last Modified: 04-MAY-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Macro Assembler (MASM), versions 6.1, 6.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

According to page 354 of the "MASM 6.1 Programmer's Guide," labels within a
procedure that are defined with a single colon are local, provided there is a
language specifier on the .Model statement. However, if the symbol used for a
local label appears as a global label in an earlier part of the source file, the
following error is generated during assembly:

  A2005: symbol redefinition

RESOLUTION
==========

If possible, rearrange the code so that the global label does not appear before
the local label.

STATUS
======

Microsoft has confirmed this to be a bug in MASM versions 6.1 and 6.11. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.

MORE INFORMATION
================

The following sample code can be used to demonstrate the problem. If "two proc"
were placed after "one proc", there would be no assembly errors and the "jmp
two" would cause a jump to the local label "two".

Sample Code
-----------

  ; Assemble options needed: none

     .model small, C
     .code

     two proc
        ret
     two endp

     one proc

        jmp two
        nop

     two:            ; error A2005: symbol redefinition : two

     one endp
     end
