The original report stumbled upon this issue with a more tricky configuration when light linking is combined with light tress. However, the actual contributing factor was a mesh with emission shader which is not assigned to any triangles. This triggered a bug in the BoundBox::transformed() which converted non-valid bounds to bounds by performing per-corner growing. Additionally fix incorrect handling of shared nodes which only worked for leaf nodes. This was due to the fact how the measure was accumulated: it is possible that add() is called with an empty measure. Pull Request: https://projects.blender.org/blender/blender/pulls/134699
