tostring produces non equal strings on script start

complete

WolfGang Senizen

Output of tostring that should be the same are not equal if done outside of "events"

function test()
    if tostring(5) == tostring(5) then
        ll.Say(0,"EQUAL")
    else
        ll.Say(0,"NOT EQUAL")
    end
end
test()
touch_start = test

Says

NOT EQUAL

in chat on start, but

EQUAL

on touch

Running luau locally this

print(`{tostring(5) == tostring(5)}`)

prints

true

String comparison in general works

local last_msg = ""
listen = function(chan, name, id, msg)
    if msg == last_msg then
        ll.Say(0, "Stop Repeating Yourself")
    end
    last_msg = msg
end
ll.Listen(0,"","","")

Says

Stop Repeating Yourself

in local if you say the same thing twice

A more comprehensive script that started this adventure, note that it works fine in the touch event

function test()
    ll.Say(0,"============================")
    local own1 = ll.GetOwner()
    local own2 = ll.GetOwner()
    
    local comp = own1 == own2
    
    if comp then
        ll.Say(0, `UUID EQUAL: {comp}`)
    else
        ll.Say(0, `UUID NOT EQUAL: {comp}`)
    end
    if own1 == own2 then
        ll.Say(0, `UUID EQUAL`)
    else
        ll.Say(0, `UUID NOT EQUAL`)
    end
    
    ll.Say(0, tostring(own1))
    ll.Say(0, tostring(own2))
    
    own1 = tostring(own1)
    own2 = tostring(own2)
    
    comp = own1 == own2
    
    if comp then
        ll.Say(0, `STRING EQUAL: {comp}`)
    else
        ll.Say(0, `STRING NOT EQUAL: {comp}`)
    end
    
    if own1 == own2 then
        ll.Say(0, `STRING EQUAL`)
    else
        ll.Say(0, `STRING NOT EQUAL`)
    end
    ll.Say(0, own1)
    ll.Say(0, own2)
    ll.Say(0,"============================")
end
test()
ll.Sleep(2.0)
test()
touch_start = test

Fixed in the most recent release. Thanks for the report and repro scripts!

Workaround: Don't create the same string twice in the same line.

local testString = tostring(5)
function test()
    if tostring(5) == testString then
        ll.Say(0,"EQUAL")
    else
        ll.Say(0,"NOT EQUAL")
    end
end
test()
touch_start = test

Have been doing some further investigation:
llGetOwner()==llGetOwner evaluates to TRUE inside of:
event functions such as touch_start & sensor
coroutines
inside of a user-defined function, called from inside of an event or coroutine
ll.GetOwner()==ll.GetOwner() evaluates to FALSE when:
In the base of a script, outside of a function
Inside of a user-defined function, called from the base of the script
coroutine.resume(detected)
comparison2 = ll.GetOwner() == ll.GetOwner()
ll.OwnerSay("Global: " .. tostring(comparison2))
dummy()
Results in:
Coroutine: true
Global: false
Dummy Function: false
