System Information
Operating system: Linux-5.4.0-7642-generic-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: Radeon Vega Frontier Edition (VEGA10, DRM 3.35.0, 5.4.0-7642-generic, LLVM 10.0.0) X.Org 4.6 (Core Profile) Mesa 20.0.8

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, hash: 4ccd5bf5c6

Short description of error
When rendering material preview icons, memory freed through gpu_node_graph_prune_unused() caused heap-use-after-free when calling codegen_call_functions().

Exact steps for others to reproduce the error
I didn't manage to recreate this in a simpler file, so here is a only slightly simplified production file (not too heavy): lookdev_funeral_01.blend

  • Open file
  • Open material data-block selector in the Shader Editor
  • Wait for some seconds
    (Enable ASan to get a proper report).
