Closed, ResolvedPublic

Description

System Information
Operating system: Win10
Graphics card: NVIDIA GeForce GTX 950M

Blender Version
Broken: 3.0.0, master, 2021-12-05

  1. Adding and working with metaballs
  2. Then, by mistake, I click on any metaball (selecting them all) instead of clicking on the radius of the metaball to select only one.
  3. Press CTRL + Z to "Undo" last step...

Program stops working.

Could you share the example .blend filoe where this happens?
note: crashes in BKE_object_boundbox_calc_from_evaluated_geometry, could be fixed already by rB6a885e5d8959: Fix meta-ball bound-box calculation reading past buffer bounds.

@Alex Lovsky (Aljnk) : could you also check if this crashes in a fresh 3.1 alpha build from https://builder.blender.org/download/daily/?

Thx getting back!

Since the fix is already on the list T93479: 3.0 Potential candidates for corrective releases, we dont need a report open for this anymore.
