Short description of error

my blender program crashes upon completing the render of the frame. does not crash in Eevee. only crashes with the grease pencil object enabled. no crash with just the cube. tested on separate PC, same crash problem.

Exact steps for others to reproduce the error

@lichtwerk Can you try to reproduce... I get the crash, but when try to debug the crash I get crashes in multiple places and not a consistent crash.

EDIT: All that I have seen running with --debug --factory-startupis this:

read exr tmp file: C:\Users\Antonio\AppData\Local\Temp\blender_a22848\grease pencil cycles test.blend_Scene_View Layer.exr
OpenEXR-readPixels: ERROR: Error reading pixel data from image file "C:\Users\Antonio\AppData\Local\Temp\blender_a22848\grease pencil cycles test.blend_Scene_View Layer.exr". Tile (0, 0, 0, 0) is missing.```

Sorry, changing it back to Needs triage as when I started to play around with the file I started to realize that it's probably not as simple as I thought.

OpenCL GPU or CPU gives same stack, EEVEE is OK

What happen if you do a single threaded render (launch withblender -t 1

The logic in RE_engine_render will need to be changed so that we load back the render buffers from disk before doing the grease pencil render.

I'll have a look at it, we need to do this carefully so that we at least avoid increasing peak memory usage for the case where there is no grease pencil.
