System Information

Intel i5-3470
8GB Ram

Blender Version
Broken: 2.79b, blender-2.79-a56ec3dfe3e, blender-2.80-ccf794dfc4c
Worked: none

Short description of error
Doesn't render this one particular project, but renders other projects just fine on GPU
this project is rendering fine on my Radeon Pro WX4100 but crashes on my RX480

Reinstalling blender (with deleting the appdata folder) doesnt help, tried a bunch of drivers: 18.7.1, 18.5.1 and 18.2.1

error messages:
OpenCL error (-4): CL_MEM_OBJECT_ALLOCATION_FAILURE in clEnqueueNDRangeKernel
and others in attached files:

blender only allocates 3.1GB on my WX4100, the 8GB of my RX4800 should be enough.
the orange brackets in the image editor are moving randomly before i get the error or blender crashes.

I'm apparently not getting any specific OpenCL error using a debug build of Blender, but I'm getting a program crash on the latest 53c56b2b5f as soon GPU scene rendering with Cycles is initiated by pressing F12, with:

AMD Radeon RX480 4GB with Radeon Software 18.7.1
Windows 10 Pro x64 (1803)

I've attached a simple file with a cube and the Renderer set to Cycles/GPU Compute. Blender needs to have the OpenCL Compute device in User Preferences set to the GPU as in the example below.

opencl-gpurendering-cycles.blend
console_output.txt

@tm9000 Please follow our submission template and guidelines, also read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue (only ONE issue per report!), precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

@s12a are you sure this is the same issue? @tm9000 says it’s also happening for him in 2.79b official release…

@brecht think you’ll want to check on those?

@mont29
Indeed what I'm seeing appears to be 2.8-specific. Sorry, this is probably a different bug.

i tried to locate the object that is causing the issue.

i appended it to a new file, rendered it and i got the error. saved it, closed blender and opened the file again and now it renders just fine. this is weird.

edit: if i append the same object to a new project again it works now. but if i try to render the main project it doesn't work.

i just found the problem:
the page file was too small (was set to 256MB), made it bigger and now it renders perfectly.

sorry :/

Thanks for testing, seems it was just running out of memory then.
