System Information:
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: RTX 2060 SUPER 457.30

Blender Version:
Broken version: 2.92.0 Alpha, branch: master, commit date: 2020-12-09 01:29, hash: 9b11a7776f
Worked: NA as ambient occlusion on OptiX was not available

Short description of error:

CUDA_ERROR_ILLEGAL_ADDRESS in cuStreamSynchronize(cuda_stream[thread_index]) (device_optix.cpp:812)

The error above appears when an object is rendered in cycles with OptiX and an Ambient Occlusion node with the option Only Local enabled.

Exact steps for others to reproduce the error:

With the default startup file, change the render engine to Cycles and enable GPU compute, ensuring OptiX is enabled in the user preferences.
Change to rendered viewport mode.
Select the default cube, and in a shader editor, add an Ambient Occlusion node, attaching at least one of its outputs somewhere in the node tree.
On the Ambient Occlusion node, enable the option Only Local. You should see the error reported above appear in the viewport in the top left. If not, try exiting and re-entering rendered mode or duplicating the cube.

I can't confirm this problem in latest master 3a23f18e02, but this might be because I don't have an RTX card.
