The follwing code shows the problem:

Code:

include 'win32ax.inc'
.code
MAX_PATH=260
proc WinMain stdcall,hInstance,hPrevInstance,lpCmdLine,nCmdShow
    locals
        unicode du MAX_PATH dup (?)
    endl
        stdcall AnotherFunction
        invoke  ExitProcess,0
        ret
endp
proc AnotherFunction stdcall
    locals
        unicode du 64 dup (?) ;<-- Error: symbol already defined
    endl
        ret
endp
.end WinMain

I think this an easy fix in PROC32 (also PROC64):

Code:

      ...
      struc dq [val] \\{ \common deflocal@proc .,dq,val \\}
      struc du [val] \\{ \common deflocal@proc .,du,val \\} ;<-- add this
      struc rb cnt \\{ deflocal@proc .,rb cnt, \\}
      ...
      restruc db,dw,dp,dd,dt,dq,du ;<-- also change here
      ...

that is not a bug, you are supposed to prefix all of your local labels with .

This is true for normally defined labels but with the locals/endl macros the labels do no need the '.'. Try it with any other data type (db,dw,rt, etc.) and it will work properly without the '.'

I didn't include DU in this list as I thought DW should be enought. DU is useful only when you define initialized data.
Since, however, the current "local" macros allow to define initialized local variables, too, this addition may be a good idea.
