Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.39

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-16 15:02, hash: 93e2491ee72487
Worked: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-16 14:15, hash: 4ca8e09b24defc
Caused by {93e2491ee724874a28030ae4d32f39bed6835923}

Short description of error
Upon completion of a render, or upon adding the group node "Lens Dust" to the compositor node setup in the attached Blend file, Blender immediately crashes with a segmentation fault.

Exact steps for others to reproduce the error

  1. Open attached Blend file.
  2. Note the attached "Lens Dust" group node in the compositor. This was attached in a build from the last working commit, listed above.
  3. In the compositor, Add > Group > Lens Dust
  4. Observe immediate segmentation fault.

I was about to report a segmentation fault while using the compositor also... not sure if it's related but I'm working on green screen footage using the keying node and when I change the feather distance value blender closes. The other way is when I connect some mask input to the garbage or core matte socket, It closes immediately. I need to use the 2.92 release to continue my work. It's working really well with the 2.92 release.
