Struct vs local name conflict

[john-terraspace]

;--- v2.18: problem if the name of struct member matches the name
;--- of a stack variable ( or a procedure ):
;--- if the structured variable isn't defined, the stack variable
;--- becomes "unknown". Worse, if a listing is to be produced, an
;--- infinite loop may be entered.

.386
.MODEL flat
option casemap:none

DDS struct
dwSize dd ?
dwOfs dd ?
DDS ends

.data

;dds DDS <0,0> ;<--- problem: the variable isn't defined

.code

P1 proc

local dwFirst:dword
local dwSize:dword
local dwThird:dword

mov dwSize, 0
mov dds.dwSize, 0
mov dwSize, 1
mov dds.dwSize, 1
ret

P1 endp

start:
call P1
ret

end start

This works as long as dds is defined now in 2.57.
There is still a possible crash/error if dds isn't declared which I've not got an immediate solution for.

Tested with listing file generation too and it seems ok.
