System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 3.3.0 Alpha, hash: d86af604
Worked: unsure, possibly dfb8c90324 worked (only tested release build, might pass silently)

Short description of error
Using a Store Named Attribute node and setting id as the name of the attribute crashes Blender.

Exact steps for others to reproduce the error

Create geometry nodes on default cube
Insert a Store Named Attribute node
Enter id as the attribute name

It crashes in BuiltinCustomDataLayerProvider::try_delete because the layer_index variable is not initialized if the name does not match any custom attribute.

Callstack: P3013

The fix looks quite simple, still have to compile and test it though.

I'm not able to repro this (in both 3.2, 3.3). Crash occurs in 3.2 too? Can someone confirm?

It's an uninitialized value, so the crash may be somewhat random.
