Seems to work fine for me.
What irritates me is that Blender tries to allocate a texture of size 2509 x 2509.

Did you try the latest version of Blender? And are your drivers up to date?

Well the 2509 x 2509 is fine because we don't actually create a cubemap but a 2D texture with more of less the same pixel count.

Jacques, the drivers of my AMD RX 580 are up to date to the latest from the official AMD website (version 18.50) and the Blender version is the one from today (i wrote it above).
The crash happens if i am in the rendered mode in the viewport and if i change the cube size of the shadow to 1024px or above, it doesn't crash if i choose 512px or lower.

I can't reproduce this on linux with my 290x and the open source drivers. Is there any reason why you are not using the open source drivers?

If not, could you perhaps try and see if that helps? (Make sure you use recent mesa versions though)

I'm using the latest drivers from AMD because otherwise, with the default AMD drivers in Ubuntu, i couldn't render in Cycles using OpenCL.
This is the driver i'm using: https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-580
This is the output of my terminal when i run glxinfo | grep "OpenGL version".

 glxinfo | grep "OpenGL version"
OpenGL version string: 4.6.13542 Compatibility Profile Context 18.50.1.418

It is possible to use the closed opencl support from AMD and their open source drivers: https://linuxconfig.org/install-opencl-for-the-amdgpu-open-source-drivers-on-debian-and-ubuntu

AMD has been working on their open source drivers for quite a while now and it has surpassed the closed source ones in both quality and speed since a few years now:
https://www.phoronix.com/scan.php?page=article&item=rx590-linux-drivers&num=1

But anyways, I guess we need to look into this regardless as it seems like the legacy opengl drivers that come with the closed drivers are buggy.

I want to test, so i installed Ubuntu 18.04.2 from zero, now there are no extra AMD drivers installed.
So, i downloaded the latest AMD drivers from their website: amdgpu-pro-18.50-756341-ubuntu-18.04.
According to the link you sent (https://linuxconfig.org/install-opencl-for-the-amdgpu-open-source-drivers-on-debian-and-ubuntu) when i run

sudo dpkg -i ...

i get the following error:

dpkg: error: cannot access archive '...': File or directory not existing

According to this documentation (https://amdgpu-install.readthedocs.io/en/latest/install-installing.html) using the command:

./amdgpu-pro-install -y --opencl=pal,legacy --headless

it installs the Only base kernel and Pro OpenCL (headless mode), should i use that command to install only the OpenCL part?

According to this (https://www.reddit.com/r/linux_gaming/comments/7lsday/psa_there_is_a_headless_install_available_for/) the answer to my question is yes maybe...

Update: using the proprietary AMD GPU drivers (version 18.50) with the command

./amdgpu-pro-install -y --opencl=pal,legacy --headless

works only with Linux Kernel 4.15 (i tried with 4.18, 4.20 and 5 but i get the same error when installing) and i don't want to downgrade to 4.15 just for OpenCL support.
So is there any mesa repository that i can use to install OpenCL?
Otherwise i will go with proprietary AMDGPU 18.50 and i will continue to get the crash of the shadow cube size.

The open source OpenCL implementation does not support the features needed for cycles to run. So that is sadly not an option yet.

AMD published a new version of AMG GPU drivers for Ubuntu 18.04.2 (version 19.10) (https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-580).
I installed the OpenCL part only and it works well!!
I think you can close this task as resolved!
