System Information
Operating system: Linux - Ubuntu Ubuntu 20.04
Graphics card: Vega 56 - Running Linux native kernel drivers (not ROCm)

Blender Version
Broken: 3.2.0 Alpha - master @ d442782dbe
Worked: 3.1.2

Short description of error
Opening flat-archiviz.blend results in a segmentation fault
Unfortunately there isn't much in the backtrace:

cat /tmp/flat-archiviz.crash.txt 
# Blender 3.2.0, Commit date: 2022-04-29 09:49, Hash d442782dbe5b

# backtrace
./blender(BLI_system_backtrace+0x20) [0xc5f43f0]

/lib/x86_64-linux-gnu/libc.so.6(+0x430c0) [0x7f970225b0c0]

# Python backtrace
<EOF>

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Download the demo from https://www.blender.org/download/demo-files/ -> Cycles -> Italian Flat
Attempt to open the file
CTD

Note the following warnings appear in 3.1.2 and 3.2.0 (so are likely unrelated):

Cannot confirm this. Both opening the file and rendering with CPU or GPU works fine here on MacOS (M1 Max) with latest master.

My guess would be 3d877c8a0d is responsible. There have been two follow up commits to fix improper casts involving subdivided GPU vertex buffers.

Do those fix the issue?

I've grabbed a more recent master (5d84d9b0d6) including the above commit(s) and cherry-picked them in to make sure that they're in the tree
Doing a clean build I'm still getting the segmentation fault so no dice.

I'm slowly working through a bisect to see where this appeared.....

So this was one of the more painful bisects, but it's related to a bump in dependencies for 3.2.x here https://developer.blender.org/T95206

Using SVN to grab the dependencies from https://svn.blender.org/svnroot/bf-blender/trunk/lib/linux_centos7_x86_64 and master I get the following results:

Works: r62866
Fails: r62892

This SVN checkout (and all subsequent) will cause the segmentation fault:

here anyway.

I'm happy to test with install_deps.sh but I'm not sure which dependencies to roll-back / check locally

Hi, can you disable GPU subdivision and then load the file?: {nav Edit > Preferences > Viewport > Subdivision > GPU Subdivision}
Perhaps same issue as in #97737 (GPU Subdivision: Crash after opening particular files)
