Change Details

**System Information** Operating system: Linux-5.12.8-300.fc34.x86_64-x86_64-with-glibc2.33 64 Bits Graphics card: AMD JUNIPER (DRM 2.50.0 / 5.12.8-300.fc34.x86_64, LLVM 12.0.0) X.Org 3.3 (Core Profile) Mesa 21.1.1 **Blender Version** Broken: version: 2.93.0, branch: master, commit date: 2021-06-01 14:46, hash: `rB383bc8d9bc06` Worked: 2.93.0 beta ba4228bcf77e **Short description of error** Blender crashes with Glass BSDF + Sharp + Linux CPU **Exact steps for others to reproduce the error** Launch Blender, set it to Cycles and CPU. - Create a new sphere (Shift - a => m => u) - Create a new material for it and change the shader from "Principled BSDF" to "Glass BSDF" - Start a render and realise you have forgotten to set some additional settings, cancel the render. - Change the "Beckmann" type in the glass shader to "Sharp", this in the properties panel, not using the nodes Editor! - Start another render, let it run a number of tiles (tried around 50, tilesize was set to 32) and cancel again for another change. - Now add a plane (Shift - a => m => p) and move that (g => z => -1) and scale it (s => 20) - Render again and once again realise a setting was forgotten and cancel the render to fix that - Select the sphere again and set a subdivision level of 5 (Ctrl - 5) - Render again and realise another setting was forgotten and cancel the render - Right click the sphere and select "Shade Smooth" and in the properties panel under "Normals", enable the "Auto Smooth" feature. - Render again and one of the steps above will have crashed Blender already. I went back in the list of archived daily build and found that build ba4228bcf77e from May 28th works as expected, build c36938297753 from May 29th and newer, including the Stable release from today, all show the crashing behaviour.... I am including a file that was created with the last working build ba4228bcf77e from May 28th, which renders fine in newer builds upon opening, it is switching steps back and forth (for example removing the subdiv modifier or changing the shader options) that will make the more recent versions crash. {F10154085} {F10154087}
