Name shadows another variable error

[Ralph DiMola]

OK this is one of my two LC headaches. The second is when you do a "save as"
you do a few things and then out of nowhere one gets the "another stack with
the same name"... thingy.

But I digress.

Peter,

Using 6.1.3 with Win XP SP3 I can reproduce the shadow error anomaly(bug?)
at will.

 1) Create a new main stack.
 2) Open the code editor for the stack.
 3) Put in this code.
-------------------------------
global rs1

command test1
local rs
end test1

command test2
local rs
end test2
-------------------------
 4) Click "Apply"
 5) Change the code to this
------------------------------
global rs

command test1
local rs1
end test1

command test2
local rs1
end test2
------------------------
 6) Click "Apply" and get the shadow error.
 7) Change the code back to the first snippet.
 8) Click "Apply" and get the shadow error.
 9) Close stack and remove from memory.
10) Create a new main stack.
11) Insert either of above code snippets and get the shadow error.

I think I have just found a reliable way to reproduce the above error.
 It's not the usual circumstance it happens but it may be enough for RunRev
to track it down.  Here's what I did (by accident):

Switch Strict Compilation mode off
Create a stack with  a few controls on it Put some simple scripts in the
card, stack and/or controls, each with a local statement that names the same
variable, say tVar.
Compile all the scripts so there are no errors in them Switch Strict
Compilation Mode on Make a change in one of the scripts and compile it - you
should get the error.  If you then try to save the stack, all the scripts
that name the variable will be get a red dot in their script editor window
tab.

If anyone has a few minutes to verify this, I will submit a QCC report and
include a test stack.
