System Information
Operating system: Windows 8.1
Graphics card: Intel HD 520

Blender Version
Broken: 3.1.2 (2022-03-31)
Caused by 64cd927519

Short description of error
The program will crash if your Python script creates a BMesh instance using the 'use_shape_key' and 'shape_key_index' parameters to access the mesh data from a certain shape key of the mesh.

Exact steps for others to reproduce the error

Create a cube;
Click the "create shape key" button a few times to add some shape keys;
With the cube selected, run the following in the Python Console editor:

import bmesh
bm = bmesh.new()
bm.from_mesh(C.object.data, use_shape_key=True, shape_key_index=0) # Crashes at this line.

Thank you for your time.

Hi @HooglyBoogly, I see that the fix was committed to the master branch.
Does this mean that if I grab any daily build from here (https://builder.blender.org/download/daily/) it will come with that fix?

The build happens at the end of the day in central European time, so yeah, the daily build should include this fix. If not, today's build would have it.
