Hi yet again,

This seems relevant in the valgrind output, I get many of them before enough damage is done to corrupt the freelist:

And then the next 14 bytes are accessed illegally one by one up to 0x468a320f.
And then a similar sequence of consecutive bytes from 0x468a3600 to 0x468a360f until we crash:

Hi yet again,

I did a build from the compatibility-develop branch in docker, and it crashes exactly the same, but now I have debug symbols :-)
The only thing it tells me though is it eventually choked on objects.bnp:

Thanks,

Drop this png to 'user' folder and see if client loads then.
https://ballisticmystix.net/temp/ld_picture_halloween_frame.png

I wrote a simple dds->png converted using CBitmap and identified 2 dds files that fail to load.

corrupted_moor_map.dds (DXT5 1536x1243)
ld_picture_halloween_frame.dds (DXT1 256x50)

Seems that CBitmap might have issues with non-power-of-2 textures in DXT format.

Hello!

#20 [de] 

Huhu all,

having the same problem I think, after the last patch, client crashes on loading screen (my toon is logged in however)

I am using the same computer as before, didnt do any system updates, didnt change any settings. The only constant that changed was the last patch.

Tried: Different toons. Same issue.
Was using Steam.
Uninstalled Steam client. Reinstalled steam client. Same Deal.
Installed Native Client. Tried throught the Native Client..Same Deal.

UPDATE: Karu's SOLUTION WORKED! OMG! Thanks Karu

This worked on my machine too!
Thank you!

I was thinking of adding some padding to the array that is indexed beyond bounds :-)

Yeah it works for me too! Big thanks Karu and Szocske for further debugging. :)
