On a test system with an older GPU I'm getting an allocation error (not enough memory) in DRW_texture_create_2d_array when trying to create a texture with the following arguments:

w = 4098
h = 4098
format = GPU_DEPTH_COMPONENT16
flags = DRW_TEX_FILTER | DRW_TEX_COMPARE
*fpixel = NULL

The crash is caused by tex being freed in that situation and the code tries to dereference a NULL pointer. If you're experiencing the same problem, there should be an error message printed to the console.

Please open Blender's directory and double click on the blender_debug_log.cmd file. This will open up Blender in debug mode and create logs file. Proceed by loading the project file and switch to rendered mode in order to make Blender crash. Once Blender is closed the Windows Explorer will open and show you two files. Upload them here by using the upload button.

Can you please run blender_debug_gpu.cmd as well and repeat the steps of loading the project file and switching to rendered mode? Thank you!

It seems that my first comment was incorrect regarding the possible cause, the log files don't match that case. I can't reproduce your crash with 2.81 or 2.81a on Windows 10 with more powerful hardware.

In order to narrow down the possible cause, we'd like you to try the following steps:

Check if you're still experiencing the crash with the most recent experimental build
With your current Blender version:
- Try to turn off Eevee features (AO, Bloom) and check if that stops it from crashing
- Scale down your entire scene, reduce the clipping values (which are currently very high) and check if the crash still occurs.
- Go through each object in the scene, delete one object, save the project to a new file and after check if it still crashes. If the crash is tied to a particular object, let us know and then try to remove modifiers and materials to check if any of these cause the crash.

I checked out all of these and here's what I found:
With the latest version it still crashes, however scaling down the entire scene considerably and reducing clipping values did help. I also narrowed down what eevee setting could cause crashing and I think it's the shadow cube size. Setting it to the highest value of 4096px causes crashing.

Did the scaling and reduced clipping already avoid the crash or was that only accomplished by lowering the shadow cube size?

Gergő commented

Scaling the scene way down and reducing clipping did in itself help preventing the crash, even with 4096px shadow cube size.

Thank you for helping investigate this! In general large ranges of clipping values should be avoided since this causes floating point precision problems.

I've informed other developers about this issue and they will have another look.
