System Information
Operating system: Windows-10-10.0.18363-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: version: 3.4.0 Alpha, branch: master, commit date: 2022-09-01 22:10, hash: 0a85288462
Broken without Join Geometry, just for empty: version: 3.3.0 Alpha, branch: master, commit date: 2022-07-12 16:47, hash: d0a552b5c6
Worked: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash: e05e1e3691

Short description of error
Blender crashes when two or more valid sources of empty (zero-vertex) geometry are joined, and then a convex hull is applied.

Exact steps for others to reproduce the error
Reproduce the node layout in the above image, and delete all vertices on the mesh.

Or, download the attached .blend file, and connect the Convex Hull node from any of the test cases to the Group Output node.
Test cases labeled "Safe" should not cause a crash, and test cases labeled "this crashes blender" should cause a crash.
JoinToConvexHullCrashDemo.blend

The .blend file opens fine on blender 3.4.1, but crashes immediately when opened with 3.5.0 alpha.

All test cases are shown here:
