Crash using texture references

For the last couple of days I've been making different tests with the next code. It draws a line of items in the screen and every icon has a tooltip to show the info of the item.

Code:

local itemFrames = {}



for i=1, MAX_ITEMS_LOOT_BAR do 

        local itemFrame = _G.CreateFrame("Frame", "LootBarItem"..i, mainFrame.LootBar)

        itemFrame:SetSize(20, 20)

        itemFrame:SetPoint("LEFT", (5+16)* (i-1), 0)

        -- icon

        itemFrame.texture = itemFrame:CreateTexture()

        itemFrame.texture:SetAllPoints(itemFrame)

        -- tooltip

        itemFrame:SetScript("OnEnter", function(self)

                if self.link then

                        GameTooltip:SetOwner(mainFrame, "ANCHOR_LEFT")

                        GameTooltip:SetHyperlink(self.link)

                        GameTooltip:Show()

                end

        end)

        itemFrame:SetScript("OnLeave", function(self)

                if self.link then

                        GameTooltip:Hide()

                end

        end)

                                        

        itemFrames[i] = itemFrame

end

This icons are updated from another method every time I find a NPC. I get a list of itemsIDs from a local table and calling to GetItemInfo() I extract the texture and the hyperlink that I use with the previous frames.

Code:

        -- hide previous icons

        for i, itemFrame in ipairs(itemFrames) do

                if itemFrame:IsShown() then

                        itemFrame:Hide()

                end

        end



        -- loop recovering 1-9 itemsMax, calling GetItemInfo() and on event GET_ITEM_INFO_RECEIVED:

        itemFrames[i].texture:SetTexture(itemTexture)

        itemFrames[i].link = itemHyperlink

        itemFrames[i]:Show()

Radomnly the client will crash while updating the icons, the most of the times if a tooltip is open (although it does happend with the tooltip close)

Here is the last log I got (If you want it complete let me know).
In this case I had the mouse on top of the first frame (LootBarItem1):

Code:

This application has encountered a critical error:



ERROR #0 (0x85100000) Assertion failure!



Program:        G:\World of Warcraft Public Test\WowT-64.exe

ProcessID:        4428

Expr:        "renderable.GetGXTex() == TextureGetGxTexUnsafe(renderable.m_simpleTexture->GetHTEXTURE())", buffer = "Frame: nullptr, STex: LootBarItem1.texture, R-GXTEX: 0000010ec5ed1b9c, H-GXTEX: 0000000000000000, IsRFallback: false, IsRStub: false, IsHFallback: false, IsHStub: false"

Yesterday this was the error I was getting now and then. After updating to the last build I get this new error more often (it doesn't give much information).

Could you post all the code that reproduces the crash?

Thanks!

I'm trying to extract a little snippet but I don't make it crash. Like the error is so random I don't know if I will be able to reproduce it without the whole addon.

Tonight it took me almost 30 minutes to see the error again with my addon (here is the screenshot, same error I posted before), for one sec I thought they had fix it with the patch they just released :confused:

Where is the whole addon?

Hello TSquared.

Thank you for your time.

Here you can see the code: https://github.com/maqjav/rarescanne...aster/Core.lua

The methods involved are LoadLootBar and LoadItemFrame.

Thanks for linking that!

We're still not repro-ing it. It's a tricky one.

What I usually do is to fly over frostfire ridge looking for rares npc. It usually crash after locating 9 or 10, but some times it ocurs after one or two. If I can give you more info let me know, perhaps the whole log or more details about my system. I hope you can reproduce it.

Hello again.

I've noticed that the bug has changed, now the error is in a different line of "CsimpleRender.cpp"

This time it happened very fast, after 4-5 npc found.

Hello, I've been testing it again tonight after the last updates and I couldn't reproduce it, perhaps luck?, perhaps it's fixed? I will keep testing just in case.

Thanks.
